This was actually the first game I played in this game jam lol, forgot to rate it though.
I like this game, its very simple and nice, it has quite a chill demeanour to it.
The movement is pretty good, it feels quite nice and is very snappy. I think the only thing that would make the movement feel better are some running dust particles and a walking sound.
The games biggiest weakness is the lack of sounds. It just punches way ligther than it should in the snappy movement feel department due to the lack of sounds. The gold pickup sound is very loud and ear piercing, I had to turn the volume down to a point where I barely heard the music but still heard the gold pickup sound, it feels more like a punishment than a good thing when you pick up the gold coins lol! Just tune it down a bit and lower the volume and it would be a perfectly good coin pickup sound.
The enemy hitboxes are quite annoying and unfair aswell, they seem to be far too wide and have a delay before you get killed + no sound for the death so it just feels extremely abrupt when the little delay happens, I do really like the text they have above their heads tho lol.
Graphically the game is very consistent and I like the artstyle and appreciate the brackeys asset :D
Here is a small visual nit pick, the floating tile blocks (Not the platforms) do not look to flattering, it looks out of place, maybe making them look more like a background and adding darker tiles under it would look better? Something like this, don't know how to explain it lol... Also some of the blocks seem to not be positioned on the grid which is just... no...

Very charming game and yes it is indeed strange to play a platformer in a brackeys game jam...
