Tip for anyone having difficulty getting the square in the spike tunnel. Pressing S very lightly does a small enough jump that you don't hit the top spikes and can easily get through with a dash afterwards.
There was an extremely stupid mistake in code. I was thinking like red worms chance to appear is 75%, but actually they were appearing conversely - 25% or less. Just stupid dev)
Splash damage from temple of inferno no longer seems to damage divers. This now seems to make level 20 impossible to get brilliant on since they're underwater for most of it.
This tactic worked for 45 and 75. Send all your jellies along the bottom orbs until you reach the last neutral one with about 75 Jellies. Meanwhile use spare jellies from the first orb to take the other one on the left. The giant blob should send down 45 jellies to bottom right lab. Wait for them to get there and him to upgrade it before sending all your jellies to it. Once you have enough, use capture power on fort above when it has 100 . You then send lab and fort jellies at once (when giant uses a load). (On 75 I took the other fort next to blob as well).
