Well you've followed the game development somewhat in the discord but I'll make mention of it here as well (gotta market the game!)

I've only used it sparingly, but it proves itself to be a great reference and standing point at how I'd make my own bullet managers to support two other unique bullets that are highly central to the game's core mechanic. So I have to thank you, truly, for showing me the asset.
If I ever get around to make more bullet hells, I'll be sure to grab the bulletfury asset from you. It doesn't do everything I wanted but it sure does a lot, and alleviates much programming stress from me!
