It was exceptionally cute, the controls were solid, and I loved the concept style (though in a lot of the areas the odd tiled backgrounds almost made me a little sick when the screen was moving), but apart from the lack of checkpoints, the gameplay was just too repetitive. I think if you made this a game with some more complex levels and turned it into a puzzle platformer or gave some power-ups and upgrades to get around/get past obstacles you would have injected a lot more variety into this and made me want to keep playing. I'd love to see this idea expanded on in the future.
