Interesting game with a silly concept, I like it! I didn't catch that I could fire the volcanoes at stuff first couple of playthroughs so I was confused on how to get past the big rocks. When jumping there was a sweetspot you can hit to get past them without firing the rock, but it was inconsistent to hit. Once I set back and read the page more I saw you can fire the volcano and was like ooo and it made it a lot easier!
l cant put my finger on it but there was something that felt off about the platforming movement. It was hard to be precise with it and make a lot of the landings I was going for. As such the game felt very difficult. Other than that I had a fun experience. Loved the art style! Great work!
