Nice, there's a lot of great things in this entry. The game feels well polished overall, in terms of animations, sound effects, deaths, menus, etc. The styling of the game is great and feeling coherent.
Some thoughts:
- The footstep, jump, and landing sound all feel a little too loud to me. It starts to get annoying after a while to hear a continual rumbling sound.
- Some of the platforming does get quite difficult. The respawn points to seem fair, however. The moving platforms suspended in the air where you have to jump between them and avoid blocks between them is very difficult. Feels to me that the platforms could be bigger to make it a little easier, or the obstacles smaller.
Good job!
