This is an abbreviated version of my review; the full version can be found in the Discussion tab. There was no way I'd be able to fit all my thoughts here.
• Avalice tried to make a level that could have fit in with 2.0's campaign - IMO, he failed
• Few rings, no alternate paths, no powerups, just a linear enemy gauntlet
• Enemies are incredibly annoying but aren't lethal because...
• There's barely any environmental hazards for what would have been a late-game level in 2.0
• Some obstacles were not thought out or tested well enough (i.e. the ejection sequences)
• Good visual setpieces
• Starting area feels like absolute hell to trudge through - forced combat plus an ejection sequence that gives no time to react
• 2 stars instead of 1 because I can see the flashes of genius in Avalice's work - if he didn't restrict himself to 2.0 limitations, he could absolutely thrive
