It's maybe tower defense at its core, but its done in such a unique fashion that it honestly never feels like that's what I'm playing. In fact, it feels completely different than anything I've played before.

There's a heart at the center, and then there's all the gross baddies trying to invade it. You're tasked with creating and connecting organs together in order to fend them off. Connect this organ to that one, now you've got a wall. That one to this one, now you've got a thorny ring of defense. The type of organs connected and even the direction you connect them from will result in different creations. Experimentation is key.

In fact with the "learn by experimentation" mechanics and overall presentation this game feels quite a lot like some creepy old science experiment you've gotten yourself into.

Tutorials are available, but there's much to learn beyond them, and at least personally I feel like finding out how all the organs interact with each other is a big draw of the experience. I'd recommend avoiding them as long as you can. (I found the sandbox mode actually worked great as a less stressful playground for finding out how things work.)

The game is frantic and fast. I die a lot, and quickly. But each time I learn more about how things work, and that coupled with the quick nature of it makes it very easy to fall into the "Just one more!" loop.

It's all a bit strange, a little creepy perhaps, and very engaging.
