I like the style of the game straight away. Not horror (I've not encountered jump-scares yet) But thoughtful and suspenseful. Everything is consistent with that theme too. The artwork, dialogue, music and sounds effects.
The UI has a good design, it was easy to find the section of the UI to equip the cards, use the potions etc.
Its actually difficult to suggest any improvements apart from to continue with the good work with the next chapter. Having said that I haven't yet finished chapter 1, but its late for me now and wanted to leave some initial feedback.
Some of the music was very loud. I did turn the BGM down in the options to 20%. However the music that played when speaking to Infoboy (after Billy spoke about his wife) started playing very loud.
Either the option for BGM got reset or that particular music is very loud.
