I like the concept here, and you've got a cute little character with a robot on their head that I really like. I couldn't quite figure out how to work this one, unfortunately. I have the sneaking suspicion that some of the UI was getting cut-off, but I can't say for sure. It would have been good to know how much health I had left, how much time / how many enemies I needed to kill to progress, and what the different upgrade chips represented. In the second wave, my robot friend decided to stop using his attack, and I couldn't quite understand why.
