lol it seems Rejet has both of our souls! I love their concepts for otoge, they're twisted at times and I love twisted games heh. Have you tried Hana Awase? and I'm familiar with all the titles you've mentioned and I'm glad we indeed have similar tastes 8Db I still need to try Koezaru omg. I loved their previous game (they made The Second Reproduction back when they're still a doujin company) and I heard from a friend that it's good, and I actually love the art! The shading especially, everything is so gorgeous <3 I'm also planning to buy Dandelion from Steam soon, I heard it's good and I hope Nameless comes to Steam too ;_;
And since we have the same taste and you mentioned DMMd, I assume you like that particular genre as well (if you know what I mean)...? If so, I recommend Shingakkou by Liar-Soft and soon-to-be-released-in-English No Thank You!!! by parade, but have great plot and highly recommended.
