Hello, hello! I think this game has potential, but I do have a few small gripes:
Overall Fun: So... the level design and platform layout was done really well. I just feel there needs to be a bit... more. Maybe more pits you have to jump across/navigate, some hidden areas, more challenging collectibles (think the giant coins in Mario - 3 per stage), and more enemy variety.
Art/Graphics: The artwork was cute. I love the main guy with the different-shaped eyes, plus the enemies were well done. The little green guys with their big noses (maybe pigs?) were cute, and I hated stomping on them haha
Controls/UI: Jumping felt... wobbly and unpredictable. Almost like I was jumping on the surface of Mars. Maybe have jumping the same height, but you get heavier on the way down. I just felt it needed a bit more weight to it. Other than that... the springs were fun, and I had no issues going from platform to platform.
Sound/Music: The music was cute and fitting for the theme of the game. I think you need to balance some of the audio, though. The music was softer, so I had that turned to a volume I was comfortable with, and then collecting fruit and the player's death audio was deafening. Especially the player's death. Turn that down a bit so you don't give some players tinnitus LOL
