100% agree, thats the thing with jams aha, scope is always a tricky thing too, cause you really wanna add alot, but then realize with how tedious and long stuff like coding and art can take, you can only manage a certain amount of stuff! like you said though, think small but make it big!!
we got stuck on quite a bit aha, mainly our save system and controls got bugged alot, even now its still kinda janky but before, oh boy- bodies would teleport to the heavens, you'd fall through the floor, I think even one time you just fell in the void aha, it's surprising how much it takes to make something as small as movement work well! Overall it is fun though, and jams like these are the best way to practice time management and make a game that's small yet fun!
Even if we dont get 1st or super high ranking overall just the fact we (and everyone else who managed) made a full game in like 5 days is impressive! Even if you're not the most proud of the final result, just be happy you made an actual full game in such a short time :D
