Really cool conceptually, but as a level, it just isn't good, sorry. The best aspect of the level is that it's fairly approachable as a top extreme demon, but this means that the gameplay is extremely basic and not very interesting to play, and also lasts a millenia, which I personally do not think works well with purely 1.0 gameplay. I do think it does a good job with the restrictions that were placed upon it's gameplay, but again, just because the concept is cool doesnt make it a good level. I'll give it credit that it does what Marathon attempts to achieve but better, but that is not a high bar, and I honestly prefer Marathon's visuals even with the really cool background Every End has. Speaking of which, the background is the only thing going on visually. I think it's a great concept and works well with the 1.0 theme, but it doesn't make the level as a whole any less underwhelming for me. This level would work better staying as a "what if" in my opinion.
