The FPS mechanics were super polished so it feels great to play, and the visuals are very atmospheric with a nice consistent low-poly feel. And I think you chose a really unique approach to incorporating mechs that makes it complements the tower defense playstyle.
Given that all the art AND gameplay was created solo I'm not surprised there were some unfinished assets but that's the nature of game jams, no points off for that. It feels great to play and I'd love to see it fleshed out.
