Really excellently polished game, impressive! The mechanic was simple and easy to understand and the movement was well done. Visually the only thing to improve on is the health/energy UI, it sort of sticks out and feels out of place compared to everything else. I almost wish there was a checkpoint before the boss, I had to play through it 3 times to beat him and having to go through all the rooms over and over just to get back was a little tiresome (at least for a game jam). Great entry :)
