Hi Jestur!
Firat of great game, but I do have one technical suggestion/obervation:
The games main loop seems so be running too fast, it comoleatly maxed out my cpu (decent gaming laptop from a couple years ago) and temps ware reaching 90°C. I had to limit my cpu to 2GHz then the game still runs smoothely and temps are back to a more accaptable 50°C
As a programmer myself I believe that a sleep command in the main loop will help (20ms should suffice) it has a negligable impact on the response times of the game loop, but allows the CPU to do other things in the meantime, (i.e. nothing). Depending on how the sleep command is implemented it might not have the desired effect. In python something like threadding.sleep should do the trick.
Perhaps more elegant might be setting an upper limmit on the FPS, if RenPy (or whichever library you use) allows for it. It should then choose the "correct" sleep method automatically.
Cheers :)
