Avis sur SpaceChem

A problem-soving game that is really difficult to finish, typical of a Zachtronics game. Your means of solving a puzzle are 2 waldos, like mechanical arms on a fixed path of your design. You manipulate atoms like it's nobody's business : bond, unbond, fuse atoms to add them up, or split them in 2, and don't mind the neutron count of atoms, those are not relevant. It gets difficult, even if you manage to handle random inputs, think of corner cases, you have to route and synchronise 2 arms to pull out the best solutions. These solutions are then statistically compared, Zachtronics-style in an histogram of speed and symbols used (also reactor count but that's pretty minor) There could have been additionnal quality of life to speed up the solving process : - when a machine breaks, a backpedal feature could give more info on why the bug happened. - coloring/marking tiles to visualize molecules in an intermediate state inside a reactor Without them, it's up to the player to process all of that in their heads, which contributes to the high difficulty. Recommended for the hardcore puzzles and the optimization processes that push you to optimize so you don't feel bad being so far in the histogram.
