Nice game! It feels really polished for being created in 10 days! Music is bangin, graphics are cute, scene transitions are well made, really good stuff!
The gameplay itself is fun too! Firing feels a bit "meh", feels more like spraying water than firing a laser cannon but other than that its fine.
But I really dig the suck feature! Where did you take the inspiration from? I feel like I seen this feature somewhere. Or I might have not I don't know but its great. You trade in the ability to fire for a few seconds for a potential large blast of damage. I also like the fact that it cannot be cheesed by being spamable, since it basically flungs the projectile into you. I don't know if thats an intentional feature or just a side effect, but its neat either way.
There are other things like the menu buttons not doing what they advertise, but other than that, the game is good.
