Great job you two! The art looks especially good!
The concept- being inside the brain of a sinner- is interesting. Wasn't able to get very far though, and I'm curious to see the full vision.
Would be great if this had a windows download, because the WebGL version seems to be a bit laggy. Every time I move things get blurry, so it's hard to move.
Because of that, I had a really hard time with the controls- but I assume it plays very smoothly either for other people or in the Unity Editor.
I recently made a 2d platformer, and this video was very helpful to me. It explains how to make platforming controls like Celeste, Hollow Knight, and Super Meat Boy. It covers things like forces, jump cuts, and coyote time. He has other ones that expand on the mechanics to teach you how to do wall jumps and jump dashes.
Klatsche_300's art looks amazing. They may not need these resources- but if they are interested they can check them out: I found this collection of posts very helpful with doing art. This video about color palettes and basically every video from this channel I have found very helpful. I'm also very interested in using Aarthificial's method for dynamic sprite updating; perhaps they would be interested in exploring that as well.
