Nice. This caught my attention because I also recently made a 3D platformer where you control a capsule.
Fixed camera and 3D perspective make it difficult to gauge the distance of things, and movement feels.. off. That made it quite awkward to traverse the levels and collect coins. I also feel that reset should happen way earlier, because watching the character fall into the void isn't that interesting, and I'm itching to retry the level.
I like that bit with reddish-boxes stacked at the end, made me retry the level quite a few times, but I got there in the end. Are you planning on updating this game?
