Amazing game coming from a person who doesn't usually play platformers but a few things I noticed and experienced are the following:
-In normal mode second level there is a bug where after reaching the end of the level there is a kernel right at the end of the path which is not registered as an actual kernel and makes it impossible to 100%.
(Which was pretty frustrating but not a major problem if you're not a perfectionist)
-In normal mode (once again) this might be a nit-pick from me but the orcs and goblins in the background feel like they're out of place and not in a certain order and the table isn't connected between them but its not that big of a deal.
(if this was intended then ignore my comment on that XD)
Somethings I would've loved to have is getting to retry from the checkpoint after finishing the level if I missed a kernel or egg from the second part of the level.
To end it off I completed every level and its genuinely a fun game, it reminded me of childhood games like Rayman Legends (unironically) and Geometry Dash which is what this is inspired from.
Would recommend to anybody who wants to have fun playing a short platformer! (And friends obviously)
