Thanks for the links Adamo!
I've tried Nishiran over the weekend, but the lack of a manual makes the game really tough at first. I had to use the walkthrough provided for the entire first level. I'm doing better now.
It feels like a DOS game running way too fast. The animations in particular are all blurry and the combats are not very interesting, what with the almost immediate 'game over' when facing a critter (feels almost like Conflux at times

) But some of the puzzles are interesting enough, and the very limited resources make it a permanent speed trial.
