Emerald Maiden is a surprisingly decent HOG that i wish was a bit longer. The HOPs are nicely balanced - not too easy or too hard. The other puzzles also offer a decent challenge without taking too long to solve. The story and environments are obviously inspired by Bioshock and this works quite well. It's also cheesy in a nice way in places (especially the bonus adventure).

€8 may be a bit steep for a <3 hour game, but you have to decide that for yourself. Honestly, the only real complaint i had was being confused at some point because the lighter i tried to pick up didn't respond the first time. Oh yeah, and developers should stop putting looping music in their HOPs. But that's it, really.
