Solomon's Key 1 (NES) and Solomon's Key 2 (NES) on Nintendo Switch Online
HARD GAMES ALERT! The first Solomon's Key is absolutely brutally hard with a life timer and counter, a game over putting the player back at the beginning of the game. Ouch. The second game remedies this a lot, allowing players to select levels individually with no in game timer.
The puzzles in both games look to be great, but super hard, and I don't think they expect everyone to 100% it by themselves. I looked up solutions for a few levels and thought to myself "I would've never figured this out". But I didn't feel bad about looking for help, it just allowed me to see what strategic movement I was missing, so that I would be able to use that style in the future levels.
