This is a pretty fun platformer, the purple "spring" was a bit hard to nail the timings of perfectly but I can admit platformers aren't my strong suit. The screen shake might be just a little too intense? Did actually make me a little nauseous the first few times. Only suggestion I could think that may help is less screen shake and add blur so it's still has the effect of disorientating the player. On the other hand it would ruin the crispness of the pixels, which are really nice for reference.
The actual running around and jumping is very smooth and I enjoy the way it feels, I don't have much experience with platformers but I can say this one was smooth at least!
The levels were real fun and I was impressed with how different each one actually felt with having all the same basic stuff. That was actually really nice. It did feel like I sorta zoomed through the game very quickly though.
As I mentioned early the art was real nice. The running animation for the little person was really flawless for how few pixels are actually being used. As someone who really prefers the less is more when it comes to game art, really nailed that. Nice and simple and not much more. The hat is a nice touch though, adds character.
Only thing I really have to mention on the audio is maybe make the button noise slightly louder when you step on it, I didn't actually notice it till the last level. It's always nice to have non visual indicators for things. All the actual sounds are good though, props to Marek Domagała.
Controls threw me off multiple times but after reading a comment on why it was done I completely understand why you'll made the choice to go with it, was a good one.
Overall it feels like a fairly good start of a game concept. Lots of different directions you could take with it. Good job everyone on the team, I feel like a post jam version could really be loads more fun, and keep up that good level design if you do one.
You all did wonderful. :) - Deer
