Thanks for playing!
And yeah, we'll be switching to taller sprites all around as soon as we are able to. They just take a lot of time and cost a lot to commission as well at least for the main cast.
NPCs we might be able to do cheaper as there will be less animations needed.
I'm honestly not super familiar with Joiplay. I have in the past been able to run the game fine on my pixel 6 and a s21 (snapdragon). Others have reported it working fine on a pixel 5, 6a and 7.
