Your UI elements don't conform to the 64x64 pixel rule, but there's still time to fix it! Your character animation is great, by the way, and I love the use of lighting.
Which part isnt 64x64? The resoultion is 64x64 resolution and i thought that was the only rule?
Your UI, the text and text/outlines on your buttons.
The outside border and the rest of the game as far as I saw are 64x64, but your UI is much higher.
Thank you! Sadly I just have no time. Hopefully its alright though since the game is following the rules <3
