Nice game, I love it, until when try to finish it with all secrets and enemies killed, turns out that cannot do that, the mega secret in Culture Divide don't count, and reading info in internet looks like other secrets neither can, and the secrets counter never will get full completed, You never can get the full experience in this game.
Run well with playonlinux, but its not so good, all weapons show the same target and was trapped many times, horrible have to see videos on internet continuously to get out from many place, buy it only if you want spend time seeking the exit of many mazes where you'll be.
You will have to click randomly in many cases to be able to play. Few sentences will be the only guide to understanding the game, I spent 1 hour on the first (easist) molecule and 10 minutes on the second. Very good game (Zachtronics type puzzle) but you will need patience and time.
