There is idea, that I should try, to make an energy pool. This energy is necessary for repulsion/attraction activation.
Energy pool capacity, restoration rate and repulsion power can be increased by means of bonuses or player characteristics growth.

coffee, what is the repulse button?
I agree with the lack of "juice", but now I am focused on the core functions, whole game structure, levels creation interface, etc.

Something like this: -- load library hump_timer = require 'hump.timer' -- create timer instance with separate update, add, addPeriodic etc functions ti...
