Alright, so. Apparently, somehow I managed to corrupt the engine that makes this game work. Doesn't stop crashing because of what looks like code errors. Though I have triple checked all the code in every object and script file, nothing looks amiss. I've also asked around in the I Wanna Community on Discord and they also don't see anything wrong per se, saying that I have indeed somehow broken the engine.
no idea how that happened but if I can't figure out a solution I might have to recreate the game in a different engine.

So for the time being, here's a newer debug build of the game that I compiled some time before everything went south.
Hope I can get this fixed soon.

Development will be on hold for the time being, have a good christmas!
