Those two are my favourites too. The one you forgot is Lost Stars probably.
Pretty weird game, alright. Well, the Techno World is actually a hack from another game, Anmitsu Hime, where the main character is a japanese young girl. Well, I believe you got stuck after the first platformer area, right?
To get the real checkpoint pass in that area, you have to go to the shrine where you can pray, and pray 100 times! Sadly, I joke you not.
