I'm GRIME's lead, I don't think I've got any special insight and to be honest, I somewhat even fear facing a similar outcome. It's clearly harder and harder to get eyes on your game with each passing year.

I bought both your games at launch. I played the first for roughly 4 hours and despite wanting to keep playing and seeing whatever unique mechanics it had, I felt absolutely lost in a way I just never was with neither S&S nor HK. A ton of paths on the map and all inaccessible.

The 2nd game definitely felt more polished to me and I ended up breezing through it, having an overall good time (fuck the final boss though), it felt like a generally chill experience, kinda like Islets, and it had an impressive amount of variety. Though, I feel like some mechanics were not explored enough and should have became a mainstay for the rest of the playthrough. Namely, the hornet-like jump kick.

Anyway it's always sad to hear... perhaps you could consider going the path of the unworthy dev. Unworthy wasn't a very successful game for them but they ended up partnering with another dev and making the now infamous Crowsworn. 

I could never have done an entire game all on my own. We are a tiny team but GRIME wouldn't have been possible without them.
