Thanks everybody! I looked at almost every entry proposed (and will look at those I haven't yet). Some conclusions:

1. Most free roguelikes have the worst tilesets and/or UI. Sorry, I literally cannot afford looking at that with my vision.

2. Paid roguelikes look funky. Wishlished a couple, will get them when there is a sale.

Shattered Pixel Dungeon ended up being my choice for now. Pretty fun.
