I LOVE IT
Not a bad game start, definitely with areas to improve but I guess it's a demo.
The game as a whole just didn't feel that polished. There were a lot of little things missing and they definitely added up while I was playing. No noticeable visual or sound effects when I stomped Goombas or Koopas, no death sounds, things like that. It just made the game feel like it wasn't acknowledging me as a player.
The actual movement of the game seems a bit choppy. Quite frustrating losing your speed once you land from a running jump. Music choice was good, even if you didn't compose it, made the game feel comfy in a way.
If you develop this into a game, try designing your own characters. The game looks promising if you can polish it off a bit and it'd be a pain if you lost credit towards your work because you used pre-designed characters.
Keep it up.
I like it. Graphics look good so far. The koopa could use some work. Seems to be in a different style. The controls seem a little bit slippery as well.
I'll definitely work on the Koopa and control issues. Thanks!
I love the sprite work! the controls took a bit to get used to, I can tell this will be a great game. Also I would like it if the enemies actually killed you! (=
Of course, thank you!
