I could always just make it so you can download your save file from the desktop application version and upload it to the browser version, but my main problem with that (apart from having to figure out how to do it) is that some people might just cheat and download someone else's 100% save file and get all the achievements.

I don't like cheating. That's not what achievements are about. They're meant to be proof of skill; to prove to others that yes, you are good enough at the game to accomplish these things.

I'll most likely just add an application to the Coolputer that allows the player to view achievements they've earned, so people playing on the desktop application version of the game can still earn them, but transferring save data will not be a thing.

EDIT: to those of you wondering why i don't just add game jolt trophies to the desktop application version, it's because i don't want people datamining the game and uploading their own false data to the game jolt page or just going and giving themself all the achievements through datamining.
