Shape of Evolution is what I call a 'Precision' Bullet shooter. Your projectile basically grows in the centre of the screen and the longer you leave it, the more effective it can be. Once you complete a level, you can evolve onto a new shape weapon. Seven levels in total, and some cheats in the readme for those that need. spacialfx.com
First, the first level is boring. Having to use the same weapon to defeat the x's after one minute becomes too much of a chore. Second, there should be a way to switch weapons. Third, an idea to recover after a short period of time would be more helpful during later rounds. Overall, nice game.
The first level were a bit boring (100 aliens, that too much !) but the last levels were nice
I liked the first upgrades (the triangle one is neat), but after the square it felt more like downgrading (expect for the last two)
The game itselft is a bit repetitive, an could use some more enemies or variations, but nice one, cheers
