Not bad! I liked the background music, and the sprites were decently drawn.
I only ran into a few issues:
- Maybe it was just me, but I felt the heart-shaped borders were a bit distracting (could make their colors a bit more dim, as to not take away from the important aspects of the UI)
- Water was a bit too difficult to come by on occasions, making it impossible to complete levels at times
Overall though, this represents a rogue-like game fairly well. Good job. :)
