Wonderful game! Concept is interesting.
I think making the arrows a solid triangle icon would make the direction easier to recognize.
Thanks for comment and suggestion Jake :D
I created a issue here: https://bitbucket.org/RokKos/pico-8/issues/4/more-visible-arrows
and will try to improve it. If you have any other suggestions be sure to let us know :D
Thanks for suggestion Jake :) We had something similar already in. We did it with pallet switching but it didn't turn out great because you couldn't see the arrows. So we decided that after game jam we will do completely new maps with new assets. So this suggestions that you listed will be quite helpful when we will do our brainstorming for new levels :)
