I can play ASCII roguelikes and have a lot in the past (mostly pre-dcss versions of Crawl and Dwarf Fortress till this day), but I am generally a fan of well done tiles. It's also why I stuck with tiles in my own roguelike.
If width is reduced, you can always get away with making the font a bit smaller. UI is kinda massive at the moment. I am speaking from a PC player perspective though, not sure how the game looks on mobile devices. I suppose these massive fonts are there because of these platforms?
Thanks for you opinion. I'll soon post screenshots of the "what you see bar" being vertical and on the right, where there's less space to display the monsters' names, so I'll see. It can be an option to turn them ON or OFF since it is easy to do.
Yes the point was that you could click on the UI even on a phone. The game is Android compatible. Even though I haven't tested in almost 2 years on a phone, I've made sure it stayed compatible.
