[REQUEST] High-down Damaku/bullet-hell suggestions please

To be clear I imply this model of recreation. This display shot is from "Wing Fighter" however the p2w curve is just too steep for me. The development on f2p is agonizingly sluggish.

I need a recreation with incremental enhancements even when taking part in ranges many occasions however improve forex is retained.

I'd a lot choose a recreation with minor IAP than outright buy, I simply don't like shopping for a recreation and never liking it. Would a lot relatively attempt a free model and pay to take away adverts or no matter later.

Thanks
