Saw this for free and liked the art style. . . lost a good chunk of my evening to it.
It's modern robotron 2084 and it is superb :D Definitely would have eaten my pocket money if it was in the arcades and was well worth a donation.
Really superb twin stick shooter. Evokes the feel of some classic Amiga games. I'm a fan of bullet hell shooters so some of the screens really scratched that itch for me, but there is plenty of variety for any shooter fan I think. Great soundtrack too if you're a fan of chiptunes.
If you put Cybernoid / robotron / and a few other shooters into a pot and mixed them, it would look something like this.
Without a doubt worth the asking price!
