I visited your site, and the game looks really cool!

It definitely seems like a unique anime game, and that's what Lemma Soft is all about. So yeah, we should trade links!
As far as the sexually suggestive content in Tales of Lemma 1:
(some spoilers, people

)
* there is some slight innuendo
* the player can decide to pull Miko's jeans down (she's wearing panties, though)
* the player accidentally catches Miko in her undies while she's changing in the morning
Overall, I think most people would agree that it's a cute, mostly innocent game. Looking back, it's probably more of a 13+ than a 15+, but I wanted to be safe. ^_^
However, Tales of Lemma 2 will be a bit more racy. (Look at the Tales of Lemma 2 page to see why.) There might even be some exposed anime breasts!

Right now it's looking like it's going to be a 16+. Future games will be all over the map, ranging from all ages to (possibly, who knows) more adult titles. If I do make games for an older audience later, say 17 and over, I'm going to put them in a separate section of the site that will be clearly marked. I'm not trying to, and I don't really have anything to gain from getting inappropriate audiences to play my games. I make sure each game's rating is clearly marked both on the download page and when the game starts up, and I give the reasons for the rating. I've decided that's the responsible thing to do.
So, if this sounds okay and you want to trade links, just let me know! Also, to other people reading this post, if you have comments or criticisms of how I handle the age ratings of the games, please post in this thread. I'd like to hear what other people think and if they have ideas on ways I might improve the system.
Thanks!
(P.S. - Tales of Lemma 2 will have improved compatibility since I've learned a lot from people's issues with ToL 1

If you post your problem with getting the game to work on the Bugs and Support forum, I can help you with ToL 1.)
