Hello!

This small patch fixes a couple of issues and adjusts several aspects regarding reviews to make more sense.

- fixed a potential issue with GUI rendering
- capped minimum purchasing power of a platform to 40% (was 0%) which fixed an issue where releasing a lot of games at once on a player-made platform would sometimes yield 0 sales
- disabled review chance decay per day (this didn't make any sense)
- increased amount of possible game reviews in a single day to up to 10 games (was 1 game)

If you come across any more issues be sure to report them here.
Thanks for reading!
