Was looking forward to trying this game out after seeing you post updates on it in the Discord!
The music is good and suits the game in my opinion, and I love how the game looks. The controls felt a bit awkward at first but I managed to get used to them pretty quickly, although it felt like there were times where I wasn't able to double jump. The sounds on the menu screen as you go up and down through the options are a great touch also!
Personally the only things I really had a problem with were the tutorial totem things. I was moving around for a little bit before I realised I needed to stop in front of them to read what they had to say. A map or minimap of some kind would also have been useful to help navigate the level as I got lost once or twice, although I understand that this probably would have been difficult to include within the time limit.
All in all I think you did a great job and I had a lot of fun playing it! :D
