I found the whole idea to be super ambitious, and the control scheme to be really innovative. I did struggle to understand what I was supposed to be doing at first, but I eventually got the hang of it. I also really liked the addition of the supplies, as they make you go outside the tank and experience that part of the gameplay before the wyrms show up! Great job!
Edit: Idk how I forgot to add this, but it looks amazing, and it’s incredibly impressive you managed to make it in only four days!
