Sort of fun, though it's a bit of a problem, that the instructions can only be seen on startup...

Please offer a no-install option so I can try the game.

As mentioned before, it's rather confusing, especially with the crusher, fireballs and bullets. It might've been better if you'd used the actual shapes, or at least a 'ghost' of the shape you should be.
That said, it's a nice first try, if you think a bit better about conveying to the player what they should do I think you'll do even better next time!

I don't like having to install it, but I enjoyed the game overall. It's difficult! :)

Nice, simple game play. Perhaps a lives system would work well here.

Good idea, but it's a bit confusing. Very difficult (i like). Good job!

Korean difficulty, sometimes you get a fireball and a bullet at the very same time.
Anyway, innovative, fun to play, graphics ... ? nah lets forget this >:)
A good little game that I would play on IPhone with a (better ?) design.
I don't really mind installing it honestly. The most annoying remains I have to reinstall to get to see instructions. -_-

Very hard game, could only come up to second obstacol.
And next time please us the "Single runtime executable (*.exe)" when exporting the game from Game Maker instead of "Windows NSIS Installer (*.exe)"! :)

Maybe Im just stupid, but to me managing the color and the shape in the same time is way too hard.
Couldnt pass the second obstacle because of it.

That's too hard... I can't even pass the first wall
