Depresiv's El Archipiélago is one of the greatest fantasy IF games in the Spanish language. After finishing it a few years ago, I wanted more, but learned that Depresiv had been silent for years before I ever discovered his few works. La Casa al Otro Lado de la Tormenta did not disappoint. The fantasy world, story, interactivity, and action kept me glued to my laptop whenever I wasn't stuck.
This is one of the first truly retro games I actually bothered to complete. I didn't even know what an emulator was. I recommend the emulator QAOP by Jan Bobrowski. It works from your browser and has buttons for saving, etc. which a lot of emulators don't facilitate so well.
I was addicted to MetaComp for two full working days. (COVID-19 had closed all of the schools in Taiwan, but teachers still had to show up. So this was a godsend.) I found the puzzles in MetaComp challenging but not frustrating. The overall game is thought provoking and obsessively fun. I'm slow on the uptake, so I missed a crucial piece in my first review. n-n very kindly gave me a nudge. He makes some of the most playable games on the Spanish IF scene. I personally love what I call "toys" in IF, and n-n's games always include neat toys to tinker with if you get stuck or if you've already beaten the game.
