Thanks! Just played through fontemon now (I think, the final battle is unbeatable right? I think I tried every move combo). Had a bit of trouble getting it to work in system programs, but on your site it worked just fine (in libreoffice it would just repeat the intro if I changed the font size, and gimp would shift things up and down depending on the highest pixel in the frame).
Overall, awesome stuff :D Ever since I read [0], I knew you could do some funky stuff with ligatures, but I never imagined you could take it this far :D
