Congratulations, this is well done. Some random feedback
- The walk animation doesn't feel like it lines up with the speed of the character, maybe you can tweak it
- I noticed (playing webgl version) that sometimes the seams between tiles would appear. I'm not too familiar with unity, but a trick that works well is to render the entire game to 1x offscreen buffer, then scale that single image up to render it to the viewport. It will give you pixel perfect rendering
Good luck on future jams
