The art is very good! I am not the best at these games so i found one sign that said 30 but it didn't do anything.
Thanks a lot for the feedback!
yeah, It's more of a thing that I didn't indicate more clearly the UI and how the progression works; the sign is there to tell you that to continue ahead you'll need 30 seconds of lifetime; so you don't try to speedrun it too much without being actually able to reach it.
I'm glad you liked the art, though! :D
