One day I hope to! But Harem Hotel has many problems in the earlier parts of the story, both from a visual and story writing perspective. (The biggest issues I see right now is all of android's story up to around level 25, and all of the dungeon content aside from F&E's)
Once everything is on the same level of quality and the game is polished a ton more with things like themed music, then I will consider putting it on steam. This will probably be around v0.20 if I had to guess, it's a lot of work to remake everything. (This is about the 5th time I'm redoing stuff now for some things)
