I have killed countless babies (ideas) throughout the jam, but none are as important as these:
In my game half of your time will be spent punching, and my fd had told me since the 3rd week starts, that i should add monster "being punched" reactions.
I wasn't familiar with unity animations and delayed making it in any shapes or forms. Turns out it is just a doShake() call and set it to operate in lateupdate and i can secure a very basic flinch animation on the boss.
My ultraman-like Giant also should have gotten a finisher move (imagine that!) but i just delayed that indefinitely for more important stuff (which i did not regret arranging my priorities like that)
Also i have always been planning to add 3d look sensitivity and invert axis to my game. I even did audio volumes settings, but never went far enough to do that sensitivity thing... And then a streamer actually needed it in order to enjoy a game. Also i still haven't published it to my friend circles because one of them also use the look camera with invert.
Luckily i have a plan to make even more games of this genre, so i look forward to one day implement all of them at once.
