I really liked the concept of this one overall!
At first I wasn't sure how loading chests worked. I saw a closed chest and assumed I needed to interact with it somehow to fill it.
On a positive note, I really enjoyed the music! It added a lot to the atmosphere and fit the setting very well.
The concept of the game is neat and I really liked the core gameplay loop. At first, I found it difficult to prioritize which dungeons to go to and sort of just wandered, but eventually I fell into more of a loop.
One hit kills felt quite harsh, especially with how fast the skeletons are.
I also found that the movement felt a bit slow relative to the size of the dungeon. The skulls helped with that, but it was frustrating having to check each skull not knowing whether it was a teleporter.
Lastly, I had an unexpected death when I teleported to a skull without being able to see where it would take me. It might be worth adding a visual indicator or some other cue to help players anticipate where they will end up.
Overall, I thought the concept was really cool and the core gameplay loop was engaging. Just needs a few minor tweaks—awesome work!
