Very enjoyable. I like how the introduction serves as a quick tutorial, and the plug mechanic is awesome, though I have some nitpicks.
- The monsters took really random amount of hits to kill, or maybe I was that bad a shot, anyway, seems like something to think of. - Aiming was a bit hard sometimes and the monsters cheating through walls was annoying since the plug has a really short range. I died a lot :) - I liked the introduction, but maybe the hero could speak a bit more? It was pretty straightforward for me to find the three orbs, but I feel like he should comment on that.
