I love the Spyro inspiration, both in the level design and visual styling. The character design is very nice, I feel like this has a lot of potential. A couple things off the bat that would make the game better, in my opinion at least, that wouldn't be difficult to implement: bring down the specularity of the textures on the character, bring down the volume of the gem collect sound, bring the camera back a bit, increase the gravity and jump force, and lock the cursor. I think reducing the size of the bigger empty areas would be nice for brevity's sake, unless you want the grandiose feeling. Also, adding another movement option, like a glide or a dash (or both!), would make the base movement feel much more rewarding. I loved this for a jam game, though, great work!
