I only managed to finish the game at the very end, so I couldn't test its difficulty and only found out how hard it was later. Maybe it won't be too difficult for some of you, but my friends found it very challenging while playing.

Wow the game was indeed very hard but it was still a lot of fun!

This is my game I will be so happy if you could try it out https://yuval6meron.itch.io/colorless-town :)
