Thank you for playing and for the feedback! I agree the squares aren't very clear. I didn't think I had time to make sprites for them to better indicate what they do. In addition to increasing the score, they also act as player buffs. I don't think they're very well balanced and should have better buffs for the player. For example, the yellow square is supposed to increase speed, but the drop rate is so infrequent and the buff so small, it is hardly noticeable at all.

Also, that's a very good point re: eventually losing. I had designed it that way so that it would definitely end at some point, but it doesn't really give control of the ending to the player. Thanks :)

Thank you :)

Thank you very much for the feedback and playing the game :) I agree the randomness of the powerups should probably be tweaked (and maybe improved bonuses a bit as well).
