Great concept and easy to understand for play sessions with kids and adults. It makes a lot of fun to play with friends. It's great how can build up your train while the game gets harder. Different mechanics in biomes, changing tasks and the greed to always get the extra bolt makes it a great game.

Furthermore the game doesn't need much resources. It even runs perfectly fine with Remote Play streaming to the TV or Remote Play Together. Since it's also released natively for Linux, it runs perfectly fine, which it didn't before using emulation layer Proton according to reports.

While the idea is great, the implementation is not. The games requires you to perform squats at such fast pace that isn't healthy. Instead it should focus on repitations where you hold a good form. This is especially important, because you cannot see your form in VR.

Furthermore, focusing solely on squatting can be boring after a while. It would be better to add short breaks and some varierty during the sessions. The second part of this game improves on this aspect, but it is limited too by only including side stepping walls.
