There definitely is an idea there. The execution (the time constraints for sure) is far from perfect. The thing that's most annoying is the inability to cancel a connection when there is no location to connect to.

I was eventually able to figure out how it works...I think. Some more instructions would be very helpful.
The node-based design is interesting, just too fiddly to use in its current state. If you keep going I'm sure you can make it into something pretty fun.

Hi! I found the idea cool, however, I didn´t manage it to come clear with the connections ruling. May be it should me more intuitional. Besides, keep on working!

I feel this concept is promising. Instructions or a couple of short tutorial levels would be great.

At least at the beginning of the level, maybe there should be fewer types of mana, so getting more types of mana as the game progresses might be a cool mechanic. If you're up for it, I think you should give your idea of combining several elements a try, in a post-compo version. Let's say you need 4 different types of mana per purifier, and a running purifier then feeds a new type of mana into a new location. You could then combine several of those secondary mana locations with another purifier to get a third-degree location and so on :)
