Damn, what a jam!
Simple premise but executed so well! I like how it started with me defending the centre and carefully picking the right coloured shots and slowly descended into franticlly rolling for my life and taking pot shots where I could. I'm glad that rolling around and spamming shots isn't as effective a strategy, it really felt worth my time to stop and quickly pick out the right colour for a shot or two and then hit the gas!
Great character design too! Each enemy having their own death cry was a neat touch. Good stuff.
