Indeed, it is very short.
Overall, I can't say that I am absolutely found of it, but there are some very good ideas, such as the key trap, or that bridge just bellow the lava level.
I am not absolutely found of the character either. But still, it looks so different from most others that it is very refreshing.

So overall thanks for what you have done !

Thanks. I'm still fairly new, as I've mentioned before, so any tips for making good levels would be great.
