The game’s music is quite soothing and it’s matches the intention of the game but the gameplay is quite hard.

I love 3D platformers. So by making that you already got a win in my book. lol. It looks nice and I do like the idea of the game. If you make it a full fledged game, you can have granny walking around so you are trying not to get caught by her while collecting everything. One downside I think is the jump is too heavy. I like my platformers with a little more hang time so I can hit those precise jumps better. 

But overall good job
