It took me a while to figure out where the health bar is (on the back of your tank), and I thought the floor was going to kill me the first time it turned red. I'd also love a way to reload my guns when I only have a few bullets left and there's no enemies nearby.
Regardless, this game is really fun so far! The panic is real when I'm running to refill my ammo hoping they won't be able to attack the tower before I get back. There's a lot of features and mechanics here that I'm excited to see when they're used to their full potential. The current main map doesn't showcase any cool ways to use the shift mechanic, but I can imagine some map designs that could have really cool places to teleport to using it. I'm excited to see more maps added!
