The art is phenomenal, the atmosphere is great and the music is fantastic! A very calm, relaxing and short game!
The controls are a little bit uncomfortable in my opinion. Whenever I see a game using Z and X as its controls I think of Undertale: Arrow keys to move and up arrow key to move. However, this game uses space bar for jumping, and that feels a little weird. You could add support to WASD and the up arrow key as a simple way to fix that! But keep in mind this is just my opinion - You may like control schemes that I don't and that's completely fine!
