That was close, just one block to get the maximum score!

The sound effects are nice, and it creates an urgency when all the blocks start to explode quickly, but I felt a lack of strategy, as I basically ran and prayed not to hit myself,

Nice audio crunchy-ness and camera shake. You spent time on the juiciness of the central thing that is happening here: I like that.

Short and sweet. Only limited possibilities for strategy but the increasing pace keeps my attention despite that.

Clear and readable visuals with a little polish.

Felt like a nice first level: would be really cool to see this lead into levels with additional mechanics, things to dodge or temporarily untouchable tiles or what have you.
