Space is the Place (Insane) is the Continuation Stage in Techneurosis, it can be accessed after beating Nuts 'n' Bolts (Insane). When completed for the first time, it will give an Epic Catfruit. Any further successful clears will yield Cat CPUs.
Battleground
Up to 3 Mistress Celeboodles appear at the start, and Maawth will spawn at 30 and 60 seconds. A minute after that, some Kroxos will spawn at a slowish rate.
Cosmic Cyclone, Galactic Overseer Nyandam, Imperator Sael and Kroxo will spawn when the enemy base is damaged. 2 more Imperator Saels will spawn over the next few minutes, and Kroxo will continue to spawn every 10~20 seconds until 12 Kroxos have spawned.
Strategies
Even though this stage only requires Into the Future Chapter 1 to be beaten, it is highly recommended to have all anti-Unstarred Alien Treasures from all three chapters before attempting it.
The main threat is the Cosmic Cyclone, so bring Castaway Cat and optionally Psychocat in order to keep it frozen/slowed, and be careful not to knock it back into Galactic Overseer Nyandam's range. Make sure to bring a heavy hitter and at least one cheap attacker in order to deal with the Imperator Saels and Kroxos.
Strategy 1
Lineup: Bony Bone, Biohazard, Noodle Cats and Catasaurus (for stage 1), Mohawk Cat, Eraser Cat, normal Macho Leg Cat, Seafarer Cat, Crazed Bahamut Cat or an Uber Rare
Not much to it, just spam Legs, and Seafarer and Necro-Dancer Cat to permafreeze Cosmic Cyclone. It might take a while because of Galactic Overseer Nyandam, but it'll be fine. Easy win.
