@honey @michael-horst thanks a lot for such detailed feedback!
@honey Yes, you are completely right, we planned to add distinguished features to help players navigate, but unfortunately we didn't make it in time, we had only 2 days. Some of the character's quotes actually were meant to give a hint when it teleportes (like 'I feel weird'), but this was done it great haste so apparently didn't work out well. Thanks for advice with different ground and torches, btw, I didn't think of it but now I understand that it would be a great thing to add.
@michael-horst totally agree about the sound, it totally slipped our mind during the jam, but after the deadline I saw how much the sound would add to the atmosphere. Gonna need an SFX designer for the next jam. Also, I suspect you didn't now that you could move faster with Shift key, which is totally my fault as I didn't add a short tutorial on controls to the game. And escape key, oh, I will write that down and put in a frame till the next jam, forget about these things every time.
