The demo was a native Linux executable. After paying the 5$, there was only a Mac or Windows full version (i feel betrayed). That one runs in wine, so i don't know, if the bugs with
- layouting on ultrawide
- text size reverts to default on history back
are because of this, but Unity games are generally no trouble on wine, except if the dev does some weird things. Since the game only has, what, 3 resolutions?, i guess the layouting issues are due to the later.
Aside from that, a few things that should be better:
- general jankiness of the interface, which lets me believe, that the dev just learned interfaces generally
- cheats should be in a cheaper option or in its own; 20$ is too much, if you only want to avoid grinding. And you don't create fans by ripping them off.
- subscription is actively checked each.single.time: store the subcription in some state file, unless you really don't want one-time payments?
- some scenes need a rework; did the elf poop in her pants while leaving the mines? walks like this: /-^-\
- too large gaps with the same still image
All in all, i think something like Ren'py would've been better suited for you. Except if you really wanted to learn Unity interfaces, in which case the most aggressive monetization i've seen in a itch/patreon game is a bit egregious.
