Nice platformer, although I'm not very good at this kind of game.

-The tutorial should point out more clearly how even a small running start will greatly increase jump distance.

-I think the rolling mechanic gets more in the way than it helps since needing to coordinate jumps with switching world's already felt pretty challenging and the rolling isn't very dynamic since you only need to use it in the tight passages.

-The part where movement keys can change a jump trajectory mid-jump often felt to be working against me, in particular in the sections where we need to jump between walls.

-Very appreciated that there's plenty of checkpoints.

-Pretty good music and graphics, love the different backgrounds in particular!

-Where's the evil AI taunting the player? I'm pretty sure there's some rule that if you're making an evil AI in a game, they must taunt the player now and then somehow.

Good work so far!

Cool game with nice ideas and good UI. However, I highly recommend improving the control scheme for keyboard. W,A,S,D is almost unplayable due to the action buttons being right below them (unless their is other button to press with wasd...in that case, this point doesn't matter) and the arrows feel weird to play with. Feels a LOT better on my Xbox controller though so its great you have support for both. Also, I'm not sure if it's because it's an HTML build, but the movement feels a bit laggy, especially when switching between worlds. Overall though, this is a pretty cool and enjoyable game. Looks like the game's development is coming along nicely!
