Nice game! I really like the concept of the falling tiles on the ground, it’s a great interpretation of the limitation!
I don’t know if the enemies’ lives should be lowered a bit or if I was just bad at it and didn’t play the right way (which is very likely haha), but I’ve had a hard time getting a score above 40. There are also several times when I did not understand why I died, but that might be because I missed some visual clue.
Anyway congrats, nice job for such a short jam and as a solo dev!
