A well-executed game. The idea is intuitive to understand, but the twist of essentially being a walking target makes it novel. I particularly like the dual purpose upgrades served; they made it easier to take out hoards of enemies, but also made the arena more dangerous and pushed the game to a conclusion. Visuals were clear and controls were responsive. I don't know if the leaderboards at the end was smokes and mirrors or actual updated player scores, but it did nudge me to play the game a few more times. I enjoyed my time with this. Congrats on a job well done.
If there's one thing I would consider changing, it's how you word the game. To quote from the games page:
"Hordes of enemies are coming after you, and all you have is a turret. But it's shooting at you?!A twist on an arena shooter, where your gun shoots at you instead."
Reading that had me going in questioning whether or not this game hit the theme of Roles Reversed. Obviously it fits mechanically, as you are the target rather than a shooter. But this framing throws things off a bit. If this is my turret, and my goal is to take out enemies, then aren't I essentially playing the same role but in an unorthodox way?
I feel that the turret shouldn't be framed as your own. That you should be painted as someone invading a space instead of someone improvising a different way to do the same job. Obviously this is a very minor detail. It doesn't even make a mechanical difference. But minor details can add up, and simple framing can change how something feels.
