Thank you good sir! This is my 39th entry to mini jam, I generally dont shy away from my usual habits so i have a pretty good understanding of how im going to do things. Under the hood its pretty quick and dirty, nothing production ready or easy to build upon, breaking a lot of design patterns too. However implementing in the quickest dirtiest (sometimes bad ways) helps me speed up.
I always start with the Art first and get all the main assets drawn up, usually takes me around 8-10 hours, then I build the assets out in engine so they all fit nicely and hook up mechanics one at a time. The longest part of it all is bug fixing and implementing audio. When it comes to Animations I use Unity Bones so i can rapidly animate things which adds a lot of polish.
Honestly though, not sure how I pulled this one off as its probably my most rounded out submission after 7 years of submitting to game jams. Thanks for the comment! I appreciate it :)
P.s I generally only sleep 5 hours a day when game jamming, the rest of all work :)
