Well done, for your first jam entry that's some top notch stuff, way better then my first entry that's for sure! I like the way you have combined resource gathering with a swarm mechanic, the UI & animations were good and the art theme consistent. Allowing the player to choose map size and seed was a great touch, and I loved the entry into the game although on replaying it, some people will probably want to be able to skip/speed that up. I wasn't really sure what to do with the green blocks, gold was obvious as it counted up. It made sense to me that the enemies damaged me outside the mech, didn't quite make sense that they did lots of damage when I was in it too, having them jump up onto the mech or some story that explains how they are able to damage the mech would have made it make more sense for me. Fun and inventive entry, excellent work to you and your team!
