Needs an update for landscape mode, at the bare minimum. Portrait mode on an iPad is doable, but not very comfortable for long sessions, especially with a keyboard case and Apple Pencil holder. It also repositions things so it’s completely different from the PC version, making it jarring to switch between the two. Also, like others, I feel it won’t be supported on newer versions of iOS soon or possibly on newer, bigger, higher resolution iPads, as has happened to other games I’ve purchased in the past - needs a compatibility update! An iPhone version would totally complete the package as well, but I can see how that would be difficult on such a small screen.
But as for the game itself, super fun, and SUPER ADDICTIVE! Saw Pewdiepie and Jacksepticeye revisit this game, never heard of it, almost blew it off due to old graphics, but MAN what a fun game once you get into it. Love it, just needs proper modern iOS/iDevice support!
