Unique idea and fire barrels were great addition! Movement was really solid and whole experience felt polished.
For improvements I suggest to improve platform designs. Not sure what exactly would be the best solution. But what i mean is that some platforms if placed incorrectly can lead to player getting stuck, since player is unable to go trough blocks, and can not jump high enough. Also some gaps are small and require crouching, or jumping mid air to get to the platform above. Of course it is probably just me having skill issue, but i felt that i constantly bumping my head everywhere and falling down if i make single mistake :D
Overall impressive work in such a short time, well done!
