I think you're onto something cool here. Like others said, with a little more time for artwork I think this game could get addictive!
I noticed you did a good job animating the text in the opening. Maybe you can pair that with some visual animations too. For example, instead of just "*** goes through the gate***" maybe you can also add an animation of the character going through the gate.
All in all, nice work. I think there is some potential here!
