Thanks for feedback. We also wanted to add some visual scary atmosphere, but we did not have enough time. About the monster we did not want any, as the athmosphere was suppose to do the whole trick :D
Thanks for feedback, if we had more time we would have added more different rooms, more objects to help player finding his way. We had idea as well of adding some lore :)
Game is cool. Is it on purpose to have the key for teleporting and opening upgrades both on c ? Because then I spend the energy even if I try to open shop from center of circle.
