Asset Forge is amazing for jams and prototypes for a couple reasons, it's fast to make many assets and everything matches visually. It has received quite a few updates since I've owned it and it feels quite complete. I've only had a few crashes but never lost any progress. Yeah I was a bit bogged down at the end with all the final parts of the game like the menus and chapters, I didn't have time to go over balance, it would have been smart to send it to friends to test part way through but I've learned that for next time :) Thanks for playing!
