I like this game! It's simple with some unique ideas. Here's my thoughts:

• I agree with colossusjak2 that it'd be nice if the floors changed a little as you went deeper. However, if you make more dungeons after the bosses, those could look different instead.

• I think enemies and traps need to cause more damage, and invincibility lasts too long (I'd half it). I know it's controversial to make the game harder, so perhaps instead you could start the game on hard mode.

• One time, I actually got the key immediately upon entering a level :D (video 1:51)

• If you press L on the start screen, you get stuck; none of the buttons work.

• I had fun trying to get to the highest floor that I could. I've run into a glitch twice (video 2:05 and 2:20) where as soon as I enter a new floor, the "floor" text in the top left does not increase, and I cannot move. I can only pause, unpause, and return to the title screen. Once, right after that problem, when I returned to the title screen and started a new game, my player was moving quickly, as if my SPD had carried over to the new game, even though it said zero SPD below. The other stats might have carried over too, but I'm not sure.

Thank you for making this game. Good luck developing!
