Finally managed to finish the game (took me a while to figure out how to beat each level), and had a lot of fun. I suck at puzzle games, but for some reason these puzzles didn't feel "frustrating", but rather challenging. It's hard to explain, but I usually give up fairly quickly on puzzle games, yet I happily played this one to the end. Definitely one of the harder games (and could definitely benefit from a tutorial, but I know how tight time is in these sort of jams).

Loved the simplistic art style, and the sound effects were great. Overall, I had a lot of fun! Good job on the game!
Edit: Typo

rage quit on level 2 but all in all a great experience!

Interesting idea. I like the fact that with each new stage new game mechanics. Pleasant minimalist visuals. I like it!

I love the art, sounds and concept, really premium. level 2 is tough!!

Very interesting concept and well executed.

I think that the exit from the levels should bring to the menu rather than quitting the game.

I hope you'll add more levels after the jam.

I Liked the game and the style of it,it was clean,but i wish the levels were a bit easier

Overall Nice Job!

cool, i like it

What I like :

- Sci-fi Mood

- Minimalist design

- Good light

- Sounds and particles

- Concept is nice

What can be improved :

- Some tutorial (I have to read the previous comment to get to level 3)

- Weapon control are complex without any reason. Simply aim with mouse down, and fire with mouse up . Could also change weapon with a short click.

- Simply change the diamond color with another shot.

- Use different shape for orbs in addition to color.

- Speed up the character

Overall the game is pretty well done, the downside are mainly due to controls. With simpler controls, the exploration of the game is easier and the lack of a tutorial can even be armless. 

Keep up the good work !

Didn't really understand how to pass the second level, sorry
