I miss these kinda stuff back in the old days man. Well, I love the sfx, and buttons feel very responsive. Pretty cosy game you guys made!
A new notes to take is that, maybe add a mechanic to prevent players from messing up there tank with misinput in the upgrading part. I was playing around the adding more hooks and bumpers, and they just straight up ruin the tank ;)) I guess a few hitbox checkers to prevent players from placing things too close to each other is good enough.
Still a good submission you guys had!
