Only good goblins get cake! Took me a while to figure out some of the tricky levels but they were really satisfying when I finally got it!! I love the complexity in some of the levels from such a simple premise!
Also really love the UI design. Everything felt really responsive and had great control with just the NES button layout. Great work on that! It was super polished. Also it was very really authentic to the NES with art and sound design.
I really don't have much critique except maybe it could use a few more tutorial levels with text to introduce the concept of killing some goblins in order to pass. Another thing was not quite understanding the win condition. Was the goal to get 5 happy goblins to the end, or was it to get a certain percentage of them? One last very minor note is wishing the level number displayed in the game too, so I could easily tell you which levels were my favorites by number! There were a couple levels I really enjoyed solving.
My least favorite level was the one with the portal maze. While I did like the portal levels in general, this one was kind of just a guessing game to figure out where each portal connected... and that just took a few rounds of trial and error to figure out but didn't require as much strategy and puzzle solving. I REALLY liked the cloning mechanic though and the "aha" moment from figuring out those levels was the highlight of my play session.
Really well done, I thoroughly enjoyed my play :)
