Nice concept! I also love the art and audio, good work! The checkpoints are SO useful :P I loved the style of the character, I wish that it could have been replicated a bit more through the environment. Maybe like having everything be those two colours (white and trey from the character) and having the elements be really bright? I think that could have added a bit more pop to the game, but I'm not sure. In any case I enjoyed playing it, keep up the good work! :D
Also I would really appreciate it if you would check out my jam entry, Sheepherd Dog. Thanks in advance! :)
