A very cute 3D platformer, the visuals were very nice, the assets were charming and well made. Great work on those! Game play for the most part felt responsive but I do have a few notes but with the caviate of "for a 3 day jam I get why you wouldnt have done all of this and this entry is still great but this is some feedback, just things to keep in mind and maybe learn from":
I would recommend looking into Coyote time, I did need to retry the entire area because of that once hehe. But it wasn't too bad here since the platforming section is short.
The other sort of big thing was that it was very hard to guage where the player was in 3D space because there was no shadow underneath them. You can check out unity decals to draw a black circle shadow straight underneath the player, it helps sooo much with jumping in 3D space An example of what I mean below where the shadow is straight below the character so you can see where you will land:
Some comments on the boss, I did need to watch the video to find out how to win admittedly. wasnt super clear that I had to dodge him till he fell over, I started to assume I needed to make him punch himself but that was brutal hehe.
Last sort of comment is that for bosses, something to keep in mind is that if attacks can all be dodged in the same way, and leave you in the same state regardless, then they are kind of the same move. What I mean by that is in this fight every attack is dodged by staying as far away as possible and running away. Not a bad move to have, but it felt like all 3 attacks were kind of the same, especially since I could stay as far away as possible.
Those are my notes! this entry is still really good all around, the platforming level kinda gave me mario sunshine secret stage vibes and was really cute! and for the most part the controls felt solid. And the assets are all very nice!
Great work!
