Is gateways worth buying?

they added a level editor now (and probably the devs are going to add steam workshop) so endless re-playability...
also, it's a fun game, not the greatest game ever, but good enough.
wait for a sale and grab it.

Depends, I'm assuming you already checked it out on the store page so you know what you're getting graphically and what not. It's actually a fairly challenging puzzle game, there are so many things to keep track of in the later puzzles that they can be hard to visualize without fidgeting about and trying out some strategies for solving them. overall it's a pretty cute game with fun puzzle/platforming gameplay
