Hello,
I think I finally figured out how to incorporate achievements. I will be rolling out an update today to see if they work for you all. Right now there are three but I will continue adding them throughout this week. If anyone has some interesting names for achievements with a description, please share, maybe I will use some of them :)
Some of the achievements are event based and then will achieve when you pass certain levels i.e. Chapter 1-4 and Chapter 2-6 those difficult ones :D
Alright that is all. I will add this to the forums for everyone to have fun and brainstorm.
EDIT: By the way, if you keep your saves, I should be able to crawl the levels you played and activate those achievement as well for you. The event ones not so much.
See ya,
Isaac
