Excellent game! This is one of my favorites so far. Can't say I've played anything like this before. Art's great (although the resolution was a little funky - had to zoom out to fit everything on my screen), music and sound were good, and you actually had time to make a story and dialogue! I hope you keep working on this.
A couple issues I had: sometimes the elevator would move so fast I couldn't click on anything in time, like when 2 ogres drop on one side. I had to know what was coming and compensate for it, which didn't feel fair. Maybe add a speed limit? Also, sometimes the little imp/goblin guys would go flying when I thought I had just dropped them gently.
