Works great out of the box besides some minor text and font issues
Text on the right side of the text box can be cut off. This happens frequently, but either a couple of letters or a word would be missing and can easily be guessed. There's a handful of times where I couldn't make out the missing text.
I skipped around in a couple of playthroughs on YouTube and noticed this problem does not appear for others, who I assume aren't playing on Steam Decks. Additionally, the font on the Steam Deck is noticeably much worse than what I saw in the videos.
At some times the animations can appear choppy. This only happened once in the demo (which is actually episode 1) and once in the second game. Both times the issue had been resolved by relaunching the game. Not sure if this is a Proton or game issue.
Good experience if you don't mind few text got cropped
The text occasionally going outside the box. Usually it's just few character to one word, so it can be guessed easily most of the time.
When you press Alt-Tab, sometimes it cause flickering between the game and your desktop/window.
This report apply to both EP1 (which is served as demo on EP2 Steam page) and EP2.
После выхода из полноэкранного режима картинка зависает, поэтому либо не стоит входить в полноэкранный режим, либо нельзя из него выходить
Нормально не поиграть после выхода из полноэкранного режима - зависает картинка. Пару раз приходилось перепроходить, так как давно не делал сохранений
By default, there was an issue with Fullscreen mode (flickering, unplayable), reverting to Proton 6.3-8 fixed it
Works just fine.
Sometimes the text goes out of the box and gets cut off, but not too often, and it's just a single word that is usually easy to understand in context. Fullscreen works.
Could full screen with alt + enter, but was stretched instead of using black bars. Sometimes text that continues too much to the right of the text box gets cut. Have not checked if these issues happen on windows as well
game in playable except for fullscreen mode
game does not launch in fullscreen with ticked "launch in full screen" option in RPG Maker menu (F1) or Alt+Enter.
