Hi ty for your submission. The game's graphics is super good! I liked the glowing buttons and planets. The text is also really cool, along with the music and sound FX. Online leaderboard is also a really good incentive for people to play again.

I played for a while and got 15 points on this. Just 3 points for feedback:

• The difficult curve for levels is too gentle. If you had enough patient the levels with 2 stages to shoot are just easy to beat. I understand the need to have a beginner level for the few first ones, but yeah, it does get kinda boring.
• The gameplay is fun at first, but it becomes tedious afterwards. That's the reason why I ended the game at 15 points.  Transition between planets is a bit too long. Procedure for the colors can be shortened by a bit.
• I haven't played long enough for the levels behind so I can't be sure about this, but I think pressing the same 6 buttons can be repetitive. I would suggest having different patterns, different grid size.

Anyway good game overall :D
