A surprisingly engaging game. I admit I looked at the visuals and didn't expect much, but just from looking at the settings, everything changed. The game does an excellent job at explaining why it's serious, which really made me completely disregard my presumptions. As a physics lover myself, I loved the many instances of using it this game had. The only coin I didn't care enough to sit down and figure out how to get was on level 7, the one at the top of the blue band thingy. I plataformed and did all sorts of amazing things to reach it, but ultimately, I was always just a bit short.
My biggest concern: The controls. They are odd, not really BAD, but odd. I appreciate being able to select the level because several times I would press ctrl + other keys and that would close the tab or do all sorts of awful things.
Other than that, an I had a great time solving all the levels and being surprised at how clever some of the solutions felt.
