Thank you for the feedback and ideas!
The outline is definitely something I can experiment with removing/editing. Originally, I wasn't sure if the character would stand out enough, but I think the lighting has solved that problem so the outline might not be needed. Will take a look!
The dash ability is also something I can/know how to add, so I'll code it in sometime. I'll see what I can tweak to make the game more engaging, and maybe learn how to create the save-load mechanics for some long-term rewards/achievements to unlock.
Super glad you like the game :D
