“The Tower of Power” is a VVVVVV level that doesn’t have any checkpoints. Yikes!
That sounds crazy, of course, but the reason it works here is that the level is so carefully designed around that core idea – it’s structured as a central hub with a linearly unlocked set of challenges as you get further and further into it, using trinkets as keys.
The really brilliant thing about it is how it makes even simple challenges feel exciting and dangerous in a way that VVVVVV levels normally don’t – there’s nothing particularly hard in this level, but the cost of failure is so much higher than usual that you’ll end up approaching it very differently.
It’s also notable for having the most extensive use of scripting I’ve seen in a VVVVVV level so far. Highly recommended!
To play a VVVVVV player level, extract the .vvvvvv file into your VVVVVV levels folder. On windows, that should be in My Documents/VVVVVV, on Mac it’s Documents/VVVVVV, on Linux it’s ~/.vvvvvv
