Really nicely done destructible terrain, and gameplay is overall pretty fun! The music is good as well. Nice to see a leaderboard as well!
Couple slight issues: the cursor was sometimes little bit difficult to see with both its size and color, at least on my 4K monitor (not flexing, just that the cursor doesn't scale bigger). There is also an issue with bullets hitting the wall prematurely, when the playable character's gun is too close to a wall.
