Feels like a good start for a survivorlike! I was able to get to level 10 before dieing.
A couple of things I noticed:
1. The map felt constricted once I got to higher levels so would be interesting if you could unlock more of the map as you go through progress waves.
2. The coins? are too large and take too long to get to player and created a lot of visual noise at the higher levels. Maybe change the shape of the coins to they aren't similar to projectiles so easier to differentiate.
3. Provide a flash on character when hit or some kind of visual indicator. I didn't really see anything.
Look forward to your next major update!
