I think I've made my thoughts on this matter fairly clear. I feel like adorable RTP sprites clash with the themes of alcoholism, suicide, and depression, which might make people reluctant to try it out. I also don't really feel it's appropriate to go commercial with RTP resources. More unique artwork like Ronove's face sets go a long way towards making it feel more unique.
I'll definitely keep following this and look forward to whatever you guys make in the future as well.
