Well, I like the idea. However it does have a few inherent flaws that one finds in 'randomly' generated worlds.
The first being that I had to try and play the game 4 times before I was even able to play it because it kept spawning me inside of a block.
Secondly as a result of the random generation it is not always possible to get to all locations from where you are. I.e. paths can be blocked or too heavily trapped to travel.
Speaking of traps there are far too many to start the game off, with the high movement speed and number of traps you quickly find yourself plummeting into the pit. And as I mentioned before there isn't always a way back.
Now these would not be an issue if the world looped back on itself, however it does not appear to. Indeed I could not find anything resembling an edge.
Also the high score board doesn't work.
It is an OK game though and for what it is worth when it did work I did enjoy playing it, I thought it was fun and challenging. The randomness keeps the game fresh but it can cause problems. A good way to solve this would be to put a time out on each coin so that you wouldn't have to wait forever for it, and to have a not so random area for the player start. I do think that the number of traps should be reduced or at least mix them up a bit so it isn't just all inverted controls.
Good concept though.
