Okay a few suggestions to make the game more playable.
1. Leveling needs to be fixed a bit. 500 is really high at the beginning. 100 is more reasonable.
2. Allow us to skip in battle animations.
3. Stronger enemies need to give more souls than regular enemies.
4. Add a gallery at some point.
5. Make the boss rooms a bit more obvious. Torches or some type of pentagram at the entrance so we know to save.
