Rainbow Cave Raid

Rainbow Cave Raid was supposed to be made for Touhou Game Jam 2021 with the theme "Rainbow", but I ran out of time. Here you go anyway though!

Play as Reimu and shoot your way through dozens of foes while grabbing as many colored items as you can to maximize your score, and face off against the boss waiting at the end! (You can probably guess who it is but I'm gonna vague about it anyway and you cannot stop me.)

Includes a whopping one stage of fast-paced shooting action!
And, maybe a few secrets as well?!
