That's a pity But indeed it isn't technically the greatest... I have played it in full-screen mode on 15" laptop with native resolution of 1366x768, and it seemed a good fit. My main PC has 27" screen with 1920x1080 resolution, and it is playable both fullscreen and windowed. I haven't noticed any extraordinary pixellation. But I actually prefer to play VNs in windowed mode on that bigger screen, since when they're fullscreen I have trouble with seeing full picture at once - I need to focus either on textbox or images. I have no experience with higher-resoultion systems.
Returning to main topic of this thread, I once again have trouble deciding what to read next... I have a bunch of recently bought untranslated JVNs waiting - like Sukimazakura to Uso no Machi, Natsu no Ame (Konno Asta's VN), Sorairo (from the makers of Amber Quartz), or the older ones like Hoshizora Planet (from Tanaka Romeo, the writer of YMK and Kazoku Keikaku) or Uminomichi (shares setting with Yukizakura's fandisc)... but then, which one?
Or maybe I should finally tackle Grisaia that has been sitting on my Steam account for almost two years instead?
Or, since I seem to read mostly various kinds of nakige recently, maybe Toradora! Portable for a change of pace? (I loved the anime)
Tough decision...
