Awesome game, maybe my favorite one from this jam. Good mechanics, interesting upgrades and brilliant bosses. Liked the graphics too. My favorite part was the bosses, all very unique and interesting. Good challenge in the last one, the others were quite easy.
Not sure if it's like this for anyone else, but the view was off in the browser version and I couldn't see some objects, for example, the lamp that led to the first place I was supposed to go after getting the moth spell. Downloaded the game and everything was fine (the underwater section's entrance was still kinda obscure tbh).
Maybe it should have been a requirement to get the dash before one of the keys? I went to the last area without finding it and it was kinda weird to go back from there. Otherwise the items were good, didn't find one of the health upgrades but did get everything else I think.
My main problem is that you can't change the aiming direction didn't always work like it should be. I always had to let go of the attack button to make it work. There were times when I did benefit from that but mainly it was annoying. Other than that this is very well done.
A minor thing also, you can fall off this screen by climbing up the left wall.
Love the game, keep up the good work.
