I have it randomly be different colors maybe the randomness isn't enough or isn't working on the demo I'll look into it when full release comes out been very busy
Noted. Also the upgrsde tree have tool tips when you hover over them I have had several testers across various resolutions . To be honest idk if you played the game or not you physically cannot pass wave 7 or 8 without upgrading.
But validate point about the length I will make the demo longer
