I never said anything about avoiding fangames, either. >^_^< I took a jump through that loophole and gave
Red a try, and... it was a bit of a thing. A bit stressful, but still a thing.
I think my biggest mistake was trying to play it at 1AM, when I was having trouble focusing and Red kept turning me into sashimi within her first few attacks.
After two attempts I gave up, then tried again the next afternoon and managed to last all the way to the end of the Pacifist path (though I had to chew through most of the food in my inventory to manage it). The game met its end by deletion soon after.
While I was playing, a problem I've been having with the Touhou games recently made itself known. I've gotten rather hefty since I began playing (no relation) and I've been having trouble breathing off and on as a result, and I've needed to pay closer attention to my lungs during stressful moments to make sure I don't run out of breath at inopportune times. Needing to dodge attacks in the manner I was doing required my full attention, and after a couple turns against Red I was left hyperventilating.
(What it boils down to is that I
really need to work on losing weight.
