thanks for your feedback! there are actually pick-ups that refill the players air and also pick-ups that increase the player's speed for some seconds but it looks like theyre not spawning for you all xD
cool game, the art looks amazing and its fun to play. just when i click retry the text of the bad guy glitches and one time i didnt have enough materials to make 10 bullets on day 1. but still a very well made game, great job!
in the hellworld you have to go to the very left platform and then doublejump onto the long platform on the right. then you can go back into the overworld
