The 4th level of the castle has some interesting gimmicks, but otherwise this is a frustrating level not worth the trouble.
The eyecandy is repetitive. You don’t have to have big open rooms on every floor. You could have made a tower a less linear layout.
The difficulty is annoying, but it’s not really hard. After running into one set of spikes, you can breeze through the rest. One room is a bunch of warps that you have to do in the correct order. Unfortunately, the warps send you straight into spike balls and there’s no way to avoid them. To add insult to injury, if you get hurt after going through a warp you get sent back because the entrance/exit is right beside it. This is where I gave up on the level. There are also coins that cannot be obtained because they’re at the edge of the level.
You might find it playable, pjshwa, but you should think of the person playing the level when you create it.
