Nice! The gameplay feels just right, and the graphics are nice and clean. Love the world map. I thought that the Coal Stocking power-up was thematically perfect, too! Everything is so incredibly polished, it's just a shame the demo is so short!
If I had some suggestions for multiplayer:
- It would be more fun if you could bump into each other or jump on each others' heads, like in New Super Mario Bros Wii. My wife and I are both good at platforming games, so we like to compete and try to mess with each other :P
- I hope there is a way to respawn if one player dies early on in the level!
Looking forward to the full game!
