Hi,
I don't know if this is a bug or a feature, but it was interesting to see my previous deaths :).
The graphics and music are amazing! I especially liked the music!
As for the gameplay, I have a different screen resolution than the one the game was designed for, so I had some issues with the game, but when I manually zoomed out it got a lot better. There were also a few caves in different levels that would take me back to the previous level, I don't know what the idea was here or if it was just a bug. I understand there is no end because I went to the place where the map ends and there is no new cave.
I also liked the opportunity to climb the wall several times by grabbing onto it.
The mechanics here are the same as in the Mario game, it would be good to add innovations.
It was fun, congratulations!
