Oups, that was your level, Flashback. I wondered why that one was in my unpublished levels so I decided to change it a little (a second version is coming). Maybe it's time to delete this :D
This level gave me quite some troubles. At first I couldn't figure out, what to do. Once, I got that, I didn't worry about how to store ''resource''. It is really painful, if you're two off in a level like this, and several times. And you KNOW, where you are losing steps, but you're not sure, how to stop it. But, that aside, I like the concept of the level.
