She's here, she's queer, and she's tsundere (I know that doesn't actually rhyme, don't @ me).
☻Coming soon in the v0.4.0 update.
Only a little of her romance is done. Cyberbird (the artist around here) is getting his wisdom teeth removed. Apparently a hammer will be involved. Please pray for him, lol. On top of that, I feel like this update will take too long if I try to put too much in. There will be some cute scenes and events with Gemma, but you'll barely get to first base with her, so keep that in mind.
Once you start "the talk," you'll have one chance to decide if you want to go on and confess or not. If you choose not to, you won't get another chance, so keep that in mind!
Compared to my previous game, I plan to have a little more tension in the romances in Hex. Nothing too toxic or anything, but each romance will have a genuine storyline with real stakes and problems to solve. Romances will progress in stages.
To start Gemma's romance, you'll need to make certain choices in the quest [Sky Magic Arc: Saga of Soul Separation]. I might make it so there's a different path to start a relationship with her later on, too, but for now, this is the only way. You'll also need a high reputation with her, which you can get by (1) performing well in combat and making certain choices during the various quests she's involved with, (2) generally being nice to her and talking to her in town, and (3) taking her out on dates. Once you have a good enough reputation you can try to confess to her.
I also intend to introduce break-up mechanics, so if your reputation with her gets too low, Gemma may dump you in a future update, so be nice to her! You will be allowed to pursue multiple romances, however, some characters (and Gemma is one of them) will not appreciate this if they find out about it.
Godspeed in wooing your mean green waifu.
