I found this to be simple in the best possible way.
All of the low-poly graphical effects and coloring felt subtle but completely direct, with an atmosphere a little bit like inscryption. The music was very calming in my opinion until I progressed and it started to feel tense despite not changing at all. Usually games like this start off hard and get a lot easier, but I feel like you kept throwing out new challenges in a way that kept me on my feet in a good way, and I had to think harder on where to place my nogs, what effects would I have to sacrifice in order to max out the points etc.
This has really great atmosphere and fun mechanics. With more nogs I can totally see this being a full game! Great Work!
