This game has some very interesting ideas. So much so that I kinda want to use some of them lol
First of all, I love how the tank effectively acts like a brawler character in a beat-em-up so to speak. The fact that you can bash zombies by swinging the gun of the tank is honestly kinda genius, and I do wish that the game leaned into it more. The gun felt inconsistent in it's use though. Sometimes it fired, but sometimes it didn't. I do like how the gun pushes the tank when it fires though. Firing the gun and then effectively YEET-ing myself into the zombies was fun as all hell.
That said, I think the way the game is structured is kind of a detriment to itself. The fact that there isn't any real time limit or anything else that's an immediate or impending threat basically means that you can freely rack up kills on the zombies without any resistance. If the aim was to make more of a speedrunning game, then I guess that's fine, but it's definitely something I feel could've used some tightening in terms of design.
The only things in the game which really felt threatening were the holes you could fall into, especially since there was ice next to them. I think the game could've used more sections/scenarios like that.
Never the less, I think this is still a pretty damn cool game overall. Kudos to the whole team since the game looks, sounds and feels really damn great.
