This is pretty interesting - it's got Getting Over It with Bennett Foddy vibes, which, if it's what you were going for, explains the high difficulty.
The art is nice, and the frog animation is cute. It doesn't feel all that fantasy, however. The menu system is also pretty well done, although the credits list didn't seem to be as intended - it only listed one person multiple times. Jumping is a little awkward at the edges of the screen as you cannot move the mouse fully, so some platforms might need tweaking, but still fun to play.
No team name, but well done nevertheless!
