I was really impressed by this game and thought the Metroidvania elements were really cool! I think there were some design choices that made things really difficult. I am not sure why the player takes fall damage when falling is required towards the beginning. The way the power ticks down makes it hard to get back to where you died quickly, this could be a cool mechanical trade-off, where the player has to be patient but I think it needs to be tweaked because in some cases it feels like there isn't enough time to get back to where you are. Checkpointing as you enter a new room could also help with this. Overall I really liked the presentation world and story here. Nice work!
