I played one round, didn't last very long. Personally, I don't like having to aim myself. I prefer the targeting be automatic so I can concentrate on movement. Also, this demo seems so limited in area that I feel it's almost a sandbox. The sprites are kind of big and move a little funny, including for my player. It feels a little too basic for me to be confident in any criticism I might have. Basically, right now, on the Itch.io website, it doesn't feel fun. And I'm using a Chromebook with a mouse, which might be easier than any mobile version using a touchscreen.
No need to complain buddy? No need to reply to my comment, either, right?
I reread the comment you replied to and played another round and my criticism is spot on. It gets crowded fast and the weapons and upgrades in no way catch up. I don't know what you mean by "won" but if it comes from the same place as "No need to complain buddy" then I'd rather not be a "winner" like you, countless or otherwise.
