Starmaker: I also tried Undertale, famous for its nonviolent path which launched a thousand thinkpieces. It actually starts with a very heavy-handed moralizing challenge: "ah, you think you're so high and mighty to try a pacifist playthrough, but when you keep repeatedly dying, your patience will eventually wear out and you'll go for the easy genocide solution, because you humans are all the same".
Now most videogames, even Undertale at its surface, have a more powerful pro-violence message than real life. Real life has no takebacksies; games do, and you can actually look at the mechanics and see which method of dealing with obstacles produces the best outcome. You won't ever know if your decision was really the best and if things could have turned out differently. But in the game, you know. You can reload, or retry, or refer to the communal experience, or look at the code. There's always the best solution, and the more "highbrow" the game is, the more it demands that you accept its best solution as true IRL.
So, in Undertale, most monsters try to
kill you to death, lethally.
Your character is 100% justified in trying to kill them. The game only works because it goes meta and save/load is part of the narrative:
you the player are immortal and have the godlike power to kill or redeem monsters, only limited by your divine patience and benevolence... and, uh, reaction speed. Because there's a stupid fucking minigame to be played in between talking attempts. Learn your lesson, disabled people, you can never be heroes and peacemakers.
The way I see it, combat in Undertale is rather abstract; what happens gameplay-wise during the enemy turn isn't an accurate reflection of what's actually going on in the game world.
Incidentally, I get the impression that Undertale is likely playable one-handed, particularly if you have a way to map an action button to something near the arrow keys. I don't think there's ever a time when you actually *need* fast access to multiple buttons and the arrow keys at the same time. Also, most of the time, you have time to move your hand between entering your command and having to dodge enemy attacks.
Also, if you actually try the genocide route, most of the game will be easy, but there are two bosses in particular that are extremely difficult, to the point of being the hardest bosses in the entire game.
Incidentally, the accessibility of games to disabled gamers is an interesting topic in itself, but is unfortunately beyond the scope of this thread.
