Phew, this is a long comment, but I really appreciate you taking the time out to leave it for me! I'm really happy to know you enjoyed Coach Grifter so much. His route was the first I did, so it's always great to see folks enjoying him~
If you're worried about moving on to other routes, don't worry! You'll see how Coach handles things in some of them. You'll see he'll be okay (it might not be clear in all routes, but Spencer's route should give the best idea of how things end up for him)!
Some of the issues you've mentioned, I'll be trying to address! The GUI buttons, I do want to see about an option to make them bigger on mobile. I'll have to come up with another solution on mobile about saving/rolling back for menus... I'm introducing a back button, but as I type this, I realize that won't help with menu choices since it only rolls back one screen. I suppose you can save after a menu choice, then roll back one and try out different ones. So you just save after the choice instead of before, hah. The Log box, I gotta fix too. It's a bit wonky on PC sometimes.
Again, thanks for much for your comment and the support of the project!
