Wow, you said that with a straight face!

It's not DRM, yet it's digitally "restricted to one device at a time".
Or to put it differently, I've bought it, yet I do not have the freedom to use it on my devices without having to deregister it from one device and register it on another.
In fact, it's as restrictive, if not more restrictive than Microsoft office. But "it's not DRM", apparently.
Dammit, I love the game. But I seriously dislike the restrictions forced on me if I want to move from PC to laptop etc. =(
This is a great indie game, and I'd just love to have the freedom most other games of it's ilk offers - DRM free, offline singler user play without device restrictions, and a/c needed only if using a server for multiplayer games.
BTW, this is the first time I've ever voiced my opinion anywhere on something like this. And yes, it's an opinion, just as you have yours. But please consider one thing - I, like others, are your paying customers. We have friends and family who might like to join us. But equally so, I know many who'd balk at the restrictions this game has.
Food for thought. I'm done now, said my piece. And shall get back to trying to get out of easy mode. Damn this game is challenging! =)
