Interesting hand-drawn art style, but a few things could be clarified to players.

PROS:

• Hand drawn characters are neat and give some cohesive charm.
• An ethereal player character is an interesting choice.
• Respawn was forgiving for whenever the player messed up.

CRITIQUE:

• It's not readily apparent what is and what isn't a platform to stand on for players. The platforms that you can stand on are blurred similar to the background and use the same color elements so I only accidentally figured out that I could stand on the tree branch leaves.
• There seems to be a gap between the two biomes right now that triggers respawn. The first time that happened I figured I needed to get a powerup or something to survive in the new biome so I was confused.
• The player sprite seems to be bigger than the plane that it's rendered on so you're getting some hard edges on the side of it where there appears to be more image. Expanding the plane that renders the character without expanding the collision box for it would help with those.

The painterly style is actually kind of cool!  Great start to a game, keep it up :D

Even successful people start from being bad to being the best.
