I'm working on an APRG called DaggerQuest. https://github.com/Laserwolve-Games/DaggerQuest
Pitch: There hasn't been an ARPG that's truly 2D in over 20 years. I'm making one.
I've made a good deal of progress and would like to onboard other developers to speed things up.
I'm using Daz Studio to make 2D renders to use as assets. I'm using Selenium Java to automate Construct itself and GitHub for version control/issue tracking/documentation.
I can dole out specific work if that's what you like, or you can just clone the repo and submit a PR for anything you like. There's a wide range of stuff to be done so any skill level is fine. Knowledge of Git would be good, but you can use a GUI.
The game is in a tech-demo state at DaggerQuest.com If the player character and enemies don't appear, refresh the page. (This only happens in an HTML5 export... Good example of bugs I find with a project this big)
