As per usual, I wasted some time on these two games today.
With Toki Tori, the same thing happened again. The level I was stuck on was suddenly easy to solve, after a good night’s rest. I solved the two remaining levels of the castle world and unlocked the next one, called Stinky Swamp, if I remember correctly. I got a new item, which I can use to suck in slugs, or just change the direction of their movement, if I only use it for a moment. I solved the first couple of easy levels and then promptly got stuck on one of the next few.
As for Titan Attacks, I got pretty much nowhere. The difficulty of the last zone is a nightmare. I’m slowly getting used to it, but I have yet to see the final boss.
