Nice work! It’s crazy how much time/work everything takes! Echoing others, voice acting and cute scenes is wild to see in jam, impressive! For the gameplay, it felt like simplifying the colliders and/or taking advantage of layers would have helped, ex having large simple shapes for the environment and characters that collide but weapons and bodies on a different layer to the daggers always hit in good spots. I also really struggled with the enemies, it was really rough only being able to move slightly faster than the zombies, and their attack range was much larger than the visuals suggest, I really wanted some dodge/dash. And sometimes they took a loooot of hits, most of the time it was a few but there was one I think I hit over 20 times before it died. It was also confusing to have broken locks to get into places then have to break the lock again to leave.
I just skimmed through your post mortem, thank you for sharing! I always write these for myself, probably should clean them up and post them too. A few suggestions: it’s ONLY the game files themselves that are locked, screenshots, cover art, all the text can be changed throughout the jam (literally just added them a few minutes ago). My process for template updates is actually changing them in game and back-porting to the template, and only doing this for the first part of the jam. I find this helps with yagni and not go ivory-tower mode. When the jam ends, I then test the template and back-port anything else I noted along the way.
Again, great job, looking forward to more!
