Very fun! I loved the platforming mechanics. The variety of different jumps is nice to have and there is enough different environmental challenges, too.
I think it's a very clever idea to include hints about where to jump and which jump to use. I never felt stuck. The game is challenging enough so I didn't feel spoiled the solution of each level. But I could see that some other players would want to turn most aggressive hints off.
The graphics look nice with very clear hitboxes which is important for hardcore platforming. Also, there are a lot of particle effects to make it look more interesting.
I didn't have any in-game audio on Windows. That's a technical issue, but I plugged in a different speaker and it fixed the issue somehow.
Overall, it's an awesome game! Great job! Good luck with your future projects!
