Very serious concept and plot! The game did feel a bit easy because of the hamsters regaining their stamina pretty quickly, thus never needing to replenish their health due to never being forced to push a hamster that far to keep energy output high enough, especially once you start upgrading them. I still did enjoy playing it though and also liked the voice acting!
P.S. I noticed while playing that the 'Skip Tutorial' text in the menu overlaps with the start game button and the hamster wheels and cages get offset when you go fullscreen, though this might not be the case for everyone due to different screen resolutions.
