This game clearly has a very large map created for it. It's a little unclear where to go — I ended up just dropping down to the bottom and trying to escape that way, before falling into some sort of infinite drop beyond the castle? Which I'm going to count as escaping. The enemies didn't seem threatening because they could be jumped over relatively easily.
The controls are mostly good, a little jerky but nothing too bad. No sounds or music, which makes it feel a little empty. The art is a little mono-tone because there's not too much colour variation across the large map. But it has fine platformer fundamentals, of jumping onto platforms, which I enjoyed.
