The game never specifically says it's mono or that you can date either Burdoc OR Malik exclusively anywhere-- in fact; it doesn't state it's a dating sim anywhere on this page, actually!
I don't feel like the game being polyam is something it needs to have plastered over every part of the game page to make it appealing; and I don't want it to be such a wild concept that suddenly "it's the hook" or that it needs warning of -- if that makes sense? I even debated for a long time including polyamorous in the tags, because I didn't want people assuming that was all the game had to offer. (Ultimately I decided it was better to include than not to. People who do relate to and need this content in their lives need an easier way to find it, and thus I included it in the tags.)
Again, I appreciate your feedback so much and I do try to do my best to let people know the content of my games/comics here on Itchio very directly -- which is super evident if you've seen any of other games/comics. But again, I don't feel like Tomai is a game that needs to or wants to shout out loud how much of a polyam game it is.
Apologies if you felt you wasted your time on Tomai, that does suck to hear since I know how difficult it can be to find content like this online right now-- but hey, at least it was free? 🤷
If somehow you did buy any of the extra content or donated to the game, I'd be more than happy to refund you! Thanks for your time!
