If you would like source, say no more. It's a bit... Spaghetti, no offense to you and yours, but I was on a time crunch, OKAY?! DM'ed it to you on Discord.
The UI will undergo a complete overhaul, I am simply waiting for the jam to end, kinda like a self-enforced sabbatical. And yes, there really really needs to be a start screen and a tutorial, those are the two things i would add if i only had two additions. I learned a ton of things this time - the most important of which is that things I make are only intuitive to me because I made them, and I really need to work on treating stuff as if there was a crazed psycho with a knife ready to stab me if he didn't understand what I'd done.
Thank you for playing, and more importantly for feeding back :D.
Also, I (completely without sarcasm) think you should do video game reviews. And I had a ton of fun picturing your mental state. :DDD
