Cute pixel art with a nice style and catchy chiptune music! I like little details like your fist being bloody after you leveled up once.
Gameplay is simple and straightforward. The monster abilities give you nice tactical choices.
If I had any criticism then maybe that the endings are too similar ;)
And on the technical side I found that
- The loading time was quite heavy and long and actually made my browser freeze a short time
- I think the handling of the 64x64 resolution might not be perfect. Everything is on the grid but the camera still moves in a higher resolution space I think
But in general I had a nice time with your little game :D
