Nice Game! Only complaints are:
1. Coins are HARD to get so make their size bigger.
2. Please don't choose colours that are hard to see (the blue enemy's bullets was hard to dodge since the colour blended too well)
3. Minimap need to show corridors or at least explored rooms.
4. Needing to point to dash is a bit strange. I like to dash based on the direction you're moving to so i can shoot and stay away but that might be a design decision. Actually I'm getting used to the dasing, sort of. The one thing I don't like about it is that you can't tell when your dash recharge. Perhaps change the colour of the triangle.
5. Breaking crates with your dash doesn't always break.
6. Continue the game, like what you did with Balls? (since it's equally addictive)
7.I reached floor 7 and it said "oh shit" below the time.
