This was an interesting entry. I like the variation between platforming and top-down roguelike-ish movement.
I feel like the movement could be improved a lot by using a few game feel tricks like "coyote-time" for the platforming section and "input buffering" for both sections. I would also consider cutting the wait the for off-screen enemies in the top-down section, because that can feel a little unintuitive too.
The rolling rock puzzles are nice, and it feels like there's a lot of space to explorer interesting mechanics there.
There's definitely room to improve, but I appreciate the creativity and variety on display, especially in solo jam project. Keep it up!
