Hey there I've actually made some Pokémon dating sims as well! Specifically I made a series of 4 dating sims about Lucario on Newgrounds.
I made the first one way back in 2015, but I kind of lost the motivation to make another. I was wondering, if you would possibly be interested in working together on a dating sim, perhaps one involving Lucario (among other Pokémon if you want) or you could just teach me how you make such awesome games. Keep up the great work my friend!
