First off, I want to say good job on making a dropper map; in my opinion, there aren't nearly enough of these, so thank you so much for making one :)
The build is really nice in my opinion, I really like what you've done with the walls, it looks quite nice. The jail cells you fall through and next to also look very well done.
The theme of a prison isn't very original compared to parkour maps, but it is the first prison dropper map.
The actual dropper itself is alright, I think it's perfectly challenging but I think that some of the drop patterns can be a bit annoying as it seems they're just randomly broken on the floors you fall through. It's not a huge turn-off, but it could be improved, at least in my opinion.
+1, good luck!
