Very cool visual and sound design. I like the minimalistic interface and the general mood of the game.
I didn't like the mechanics of QE, especially the throwing away of items. The idea is good, but the implementation is not very good. I don’t like that there is a risk of accidentally pressing E (out of habit, like interaction in other games) and losing an item somewhere in a dark place along the way, then you will have to look for it all over the map. Once I caught a bug: I dropped it in an inaccessible place, couldn’t pick it up and had to restart the game.
IMHO If the game does not use the mechanics of dropping an item to solve puzzles, then it is better to remove it completely. Perhaps it’s better to let the items be collected in the inventory which can be opened with “tab” (instead of the space bar, as now), and with the help of QE they are not thrown onto the floor but simply scrolled through, and when you hold Q or E they are hidden in your pocket.
