Good art style, the controls really need refinement if you want to have precision platforming. The inertia feels good and it encourages forward momentum, but the level design doesn't support you holding right and precision timing your jumps. If you want to keep the control scheme the level design needs refinement. If you want to keep the level design, the controls need to be more responsive.
The story and vibe are good. All in all a good first game with only some of the problems you would expect in a first game.
