Wizard's Tower [2x2]

Can you escape before the sun goes down?

I present you my new conceptual map: a 2x2 size track using only vanilla blocks. It was a pretty tough challenge, but even in such a restricted area, there are many possibilities.

First it was supposed to be a checkpointless track, but I decided to add CPs where I could to make it more playable.
Map contains 4CP, one is bit longer.
