yeah, it works now.
Gameplay is pretty basic, but this is ok for a beginner.
I discovered an area where tiles cover the player.
The music was funky but stopped playing after a while. It needs to be set manually to looping (though this can be easily overseen, and it happened even to me but then fixed it after my first playtest).
Otherwise I quickly killed all enemies, no new ones were spawning, they were not attacking back, and I missed a win message / screen that the objectives have been reached.
