The player/slime art is nice enough, and I see what you were going for, but this is unfortunately quite lacking in execution. I don't take much issue with the relatively simple gameplay, although the jump controls and attack hitboxes could have been tweaked slightly like others have said. But I think if you were leaning into atmosphere like it seems you were, more balanced art execution would have been appreciated. It's hard to feel immersed when you're on a plain blue background with floating green platforms in complete silence. I'm sure some of it is time-based, which will improve as you continue making games for jams, but this is not a bad start by any means. I would have also liked a little more guidance as to what the goal was because I was pretty lost at first. Even if you don't have time to put it in the game, more of a description on the game page would be helpful.
