The puzzles and character dynamics in this game are surprisingly well thought out. I found myself genuinely engaged in this entry.
I think the biggest issue I have with the current version is with the tank controls and… well, controls in general. I feel like the bone-to-plate mechanic was not introduced well and when I took the hint after some time, I was just frustrated.
When you introduced fire, the characters really started to feel distinct and I understood what you were really going for. The puzzles began to flow a lot better and solving them was satisfying.
I think I would recommend getting an artist on board and putting together a brief commercial game out of this– this isn’t just a little tech demo or test, it’s a full blown minimum viable product. Congrats!
