seems like it would have potential as humor and eroticism varying from innuendo to porn depending on where you want to go with it. Consider that in Zelda the main character is always doing theft/home invasion type stuff, therefore they could probably use a spanking and those upside down hearts look sort of like butts so to start 3 swats would put an end to their life of crime against the poor dungeon creatures, at least until they collected more butt containers to increase their endurance...

There needs to be a way to top up payments, then in your example if the dev if the dev converted a free to a 10$ game with purchase to donation conversion the 1$ donator would then be able to top up with 9$ to reach the 10$;

or if a dev released a version 0.5 game for 6$ then added a tier of 7$ for version 0.6 the customer could just top up the 1$ instead of having to rebuy the game at full price again.

bought 8$ tier, then dev released a 9$ tier, i didn't see a way to top up from the existing download link at top that appears when you are a customer, tried buying 2$ tier to see if it would add (bringing total to 10$) but it considers the 2$ a separate purchase...

next time you patch, naming the download file by the games title instead of just "game" would help keep the file from getting lost in peoples download directory, thank you
