Considering that it is a first time jam, it was made very well! There are some things you can improve here, like at the dialogue is a bit quirky? I do not know but i felt like reading the dialogue is a bit too weird, like not the common dialogue in common games. The puzzle is good, i love playing puzzle games but it would be good to know which platform opens what, because all i did was just to ensure the normal rock goes to these platform at least once and it might open a path somewhere and it is. The ending also quite weird, i was hoping i get a closure on the story but i got more questions than answer, the story direction needs to be clearer. Theme-wise is not on point as well, yes i will sacrifice my power up when i go to the next level, but at that next level i gain back the lost power, so the removal is a bit meaningless, saving the soul is also possible so no sacrificing must be made at all. With that in mind, congrats on your first jam!
