How to unlock other weapon

Hi there! You can unlock another weapon and another movement ability by completing the two optional levels in the three-level cluster. Then you can equip them in the bottom-left button :)

usual movement and second weapon OP as a duo

i love this aesthetic, what style would this be? 

game is not working for me when i click play the game just crash


Wow super clever game! Very intuitive and fun to play

you should be able to skip the intro tho

super fun game! 


the second weapon is ridiculously broken.

Let me explain

The first weapon

- punishes you for playing safe

- has a shit damage output unless you live dangerously

The second weapon

-rewards you for playing safe

- has a ridiculous damage output.

My suggestion - make the first weapon have a slight damage curve.

nerf the damage output on the second one

seriously, it wasn't much of a grind to do all of the bosses hitless.


hi, thanks a lot for the input!

for this demo, we wanted to try out what would the game look like if we added a weapon that rewards a safe gameplay style. Before, this weapon would do more damage the faster you were while picking it up (therefore, also rewarding danger), but we wanted to give iteration a shot.

being honest, I am not extremely happy with how that specific attack turned out, and we will definitely tune it for the final game

thank you for commenting, and I'll raise this up again to our designer!


your obb game is so good can you make a game out of it please?


Wow, that was really cool.


Clearly a gem, great mechanics, feedbacks, gameplay.

Awesome !

good game, but it becomes slower and lagyer when im in fullscreen and fast but hard to see in outscreen (or without fullscreen I should say?)

have you tried playing in low gfx mode? on the pause or start menu just untick the high gfx checkbox.

yes and on without it


Dude, this is sick!

Solid design and aesthetic. Think balancing could maybe be changed a bit. Great game.

hi! what do you find off about the balancing?


That was pretty good


great game, the music and sound effects fit so well and the mechanics are simple but really fun

This is a great step up from the original game, and I'm glad the spinner problem got fixed !

YES i did triangle

Good job!!


amazing game



3rd one is pretty hard but you get better when your used to it

anyways great game!

For some weird reason i felt the last level easier than the square level, anyways, this is a hard and fun game :D


is is a great game, good job!


This design is so elegant! The concept is really well thought, and served with some amazing juiciness! It just provides incredible sensation.

I thought I would be forever stuck on the last level (triangle), but eventually achieved to beat it with the bonus attack. The game becomes quickly difficult, which I guess is by choice. And most of the time the challenge is actually really satisfying! However, it comes with some frustration too. Many time I had the impression that I failed not because I didn't reacted fast enough (although it did also happen), but because I took a bad decisions 1 or 2 seconds ago that brought me in a situation where I couldn't win. And this didn't feel really great. There are even some obstacles that I couldn't find how to reasonably avoid, other than with cheer luck (mostly when it involved aiming missiles, or too many "rockets" coming from the center with no readable order).

Still I enjoyed completing it, and playing with the two alternative controls! It's an intense  and unforgivable game, but that can quickly become addictive. I found displaying the remaining health on defeat is a clever choice, often giving a little hint that beating the level might be actually reachable. This demo was already quite fun, i'm curious to see the final game!


This is incredibly insightful, thank you very much for posting it! <3

We will definitely keep an eye out for making the game feel as fair as possible!


also yes, 1 bug that when u died you cant restart

Last level sucks

I love that game but I wish there was like a phase shift ability or something that makes me continue in the zone because I love when the game speeds up but I have to tap because levels are design not to reach that high speed. I think you could add a phase shift ability that make the player phase through the red areas but the ability runs for like 1 second or something and need to cool down but also if you successfully phase through something, you get right away. I wish the game allow high skilled player to have combos and make the main character run on high speed with max damage.

overall, great game :)


Hey! Im not sure how much of the game you played but if you defeat all three of the bosses in the cluster around level 4 you should unlock an ability like that :)

I might have missed that :( because it gets so hard before reaching that level

Fun game I have high hopes for when it comes out as a full game

That's awesome to hear! Thank you <3


Good game to play for those who are looking for reaction time challenges.

My recommendation is that:

There should be indicators on where the player should move the spacecraft on the map in the beginning levels of the game. I got confused by the "What?" and "Start" squares. As a new player, I thought that the Start square was the beginning of the level so I tried hovering towards the left to see the other levels.  

Also, there should be an indicator in choosing the upgrades. I suggest changing the colors or other creative methods for the color-blind people to determine if the upgrades worked or not.

It is a fun and challenging game with a few tweaks it is going to be a huge hit. 5/5

Hey! Thank you very much for the feedback and your ideas! We will definitely take those into account, and we will definitely think of how to best tackle color-blindness for the final release


Cool Game Dont know how to change the equempint do they have to be blue to equip it?

They should appear as dark blue if you have unlocked them! A small black bar will appear to the left side of the ability you have selected :)


cool game I feel like there should be an arrow pointing to the rotating square saying "this is you" as I was a little confused at the start

This would be the perfect mobile game!

Amazing graphics, simple but fun gameplay, just overall good :)


Also the dash is so cool



Nice 1st place on "the obstacle" (level 3)! Brilliant game that I am maybe only partially biased towards due to my ranking


It's incredible


Super fun! This game reminds me that simple is hard :)

Lessss Goooooo #1 on first lvl!


A fun fun and simple game; But there should be a direction indicator on the obstacles so I'm not playing a guessing game.


Great that you can create such an interesting and challenging game with just one player input. Fun!
