Sweet—glad you're enjoying it! Since you've played a bunch with other people we'd love to hear any feedback you have about the gameplay, balance, power-ups, feature requests, etc etc. We're working on some small updates to the game now, so maybe there are some quick changes we can make if you have some ideas. We're both on twitter - https://twitter.com/flukeout and https://twitter.com/secretrobotron - not a ton of updates though as making this game was a hobby project. We'd love to work on a new game again though. Cheers!
