3/5 because it's a game that works and has potential. I like the "bullet steal" but I didn't understand when it was available. Some areas that can be improved are: pause when in menu, sound and music, reset game when starting new, make text prettier.
There is a way to get more time. It's not obvious but it's not difficult. (that shouldn't spoil it for anyone)
The blocks have different amounts of slipperyness I think; some surfaces act like ice...
Anyway, the game is incredibly frustrating. But I'll give it another try.
Simple game, but it has good feeling. The boss could use some animations to show when it shoots. It seems the enemies have very good traction, a little unfair :)
