Thanks for playing!
Yeah I actually tried to discourage click spamming by having the energy drain really quickly, but maybe there's a better way to do it. The music was written by our amazing composer FidelDelgado.
As for the theme, if you walk around you'll see that the map is a wrap-around in both horizontal and vertical directions. So the level is actually equivalent to a donut shape, that's why I called this game TubeWorld ;) (I initially planned on having a minimap of a donut just to show where the player is but I ran out of time haha)
