Sure! But I don't have the beta, so could you give me a list of the levels? I can add them in ASAP.
Bit late, but level list is as follows. Might be worth waiting for full release though for a complete list if any are added.
kickstart alley corridor drop subway jump shots dog1 fightclub desperado break dog2 tiralley serv hospital donut elevator dog3 oldboy ballroom meeting hacker
Ninja-Edit: Probably best to say timing starts when you select the level and ends on the words SuperHot appearing once the level is over and everyone is dead.
Oh crap, I didn't see this for a few days =/
But I added them all, as you listed them! Feel free to do some IL's ^-^
Will do. Again, new levels might be added in the full release on 25th, I'll post them here if there are any.
EDIT: Was just about to try some ILs, better wait until full release in case some levels are faster in BETA.
