"This game is free but the developer accepts your support by letting you pay what you think is fair for the game".
Even through I always happy to support other decent developers, PayPal stopped working in my country due to the fact that I invaded Ukraine (oh yeah, no any doubt I personally did it!) and a card of my bank is also unacceptable for global payments. I'm sorry I can't help.

Now about the game. It is... relaxing and chill. Good for wandering aimlessly for 5-10 minutes. But the goal is not clear. Should I find something special to interact with, get out of a "maze" of environment, or something else?
