A nice set of random games to switch between an d a really interesting art style to go along with. A mix of hand drawn and a 3D environment to give it some context is a great idea. And I really enjoyed the different drawings for the games and such.
One thing I wills ay though is that the lighting looked a little off on some of the 3D parts. As well as the texturing on the stars, at least compared to the relative drawing realism of the paper.
Also some of the games were definitely easier than others, which to be fair is kind of the point of the randomization and makes it more interesting than if they were all just as easy. What I will say though is that the "space invaders": style game, was quite difficult if you die because of the fact that the bullets do not despawn on death. Which means they will hit you 3-4 times before disappearing. Which leads to quite a lot of a deaths and lost runs due to a bullet constantly murdering me.
