It's a really cute game with a nice mixture of pixel art and a 3D environment. The shader is really cool as well. Unfortunately, I was a bit lost with the objective and I would have loved to have a small tutorial in the beginning, especially because I had to find out how to use stuff like the telescope by trying out.
It has real potential but I would think it would be nicer to have a bit smaller map.
Keep up the nice work :)
