Thanks for playing & feedback!
Good point regarding the difficulty, this was something I wanted to fix, but I didn't had enough time for that. I'll keep this in mind for later versions of the game :)
A neat, simple and fun 3D platformer - good job so far! :)
As BenFontaine & WigHz already mentioned, the contrast is quite low on my side too. Some more colorful environment would give the game some smoother and more polished touch. IMHO the coin pickup sound volume is also quite low, which confused me during the cloud sequence in the middle of the game (at least I wasn't sure if I collected a coin or not).
Overall, I had some fun while playing your game and was quite happy to see the boss :)
As already mentioned this game doesn't fit with the theme of the jam, but besides that you really implemented a bunch of interesting ideas and mechanics.
Some notes from my playtest:
A nice little platformer game and well used theme & wildcards! I like the art style, the controls are quite self-explanatory and it feels like a little teaser for some more :)
Just one minor note: In my first run I was not 100% sure what to do or why I died, but I realized the goal of the game in my second run.
As the others already mentioned this game provides an original idea (ingame menus as gameplay objects) and the mechanic is pretty neat! The music is also quite relaxing :)
Some kind of tutorial would be a big improvement here as I didn't know that I can actually move the menu buttons.
Overall, a quite good mini game with future potential!
