It is not my game, I just use/like Unity so I just wanted to point out that most faults are not by the engine itself but devs.True But no big AAA game ever run my gpu so hot that some small unity games did. Most of the times you can force vsync but not always.
And there are plenty of games on unity that i love (Shadowrun series, and Slay The Spire comes to mind) and they work flawlesly since clearly competent people were working on it; but i always have "refund" option on hand when buying game on unity when it happens to try and kill my PC for no reason.
Oh and this is not a hate on dev of this game or anything, if he done things properly (and from what he said he probably did, so sorry @Winterfire if it seemed i was personally attacking you or the game, that was not my intention) it will work fine and i will be glad to play it... i was just burned by this engine so many times im instantly weary when i see game on it. I guess i just see Renpy as a perfect engine for those type of games from my standpoint.... but hey it could be worse, it could've become RPGM game
-edit-
Woops, you did say "he", I am blind
