Game's amazing and I could get the hang of it in a matter of a few days, I like the little added challenges but thankfully they all involve dexterity based skills and not additional memorization :D
Yup, I can't seem to get an S-rank on the anti-grav day despite passing Captain's order perfectly, I tried at the least 10 times before giving up, S-ranked all of the other days too
Also, there's another bug when I start a level (I presume any level) where the tray starts shifted to the left side, on top of the grill, and the client's timer and dialogue begin's immediately, overlapping Tentacle's guy's starting dialogue. It happens I'd say 1 in 10 chances.
