The idea itself is really cool, and probably for those who can master it the anchor slingshot is super fun, sadly my brain could not really get used to either the controls os the slingshot, so barely used it and broadside fired at everything. Upgrades were interesting and ship vareity was nice!
While the overall graphics representation is neat, I do feel like that the bullet particles would quickly ran out a gb from drawing calls, that said here it is no issue.
Sadly no music, sounds effects were okay!
overall a cool idea, nice implementation!
