Skill 3 demos
I love this kind of stuff, but it felt a bit too soft, like a long tutorial that never really tests you. Though I guess that was the point (an exploration-heavy obstacle course). Dodging traps over a pit and being greeted by an ogre - that worked, wanted more of that. Looking back at "Airgapped" - it had moving platforms, layers, swarms of enemies - things I feel this should have built up to (except 4 times less cramped).
Really liked how open that last castle level was.
The "flappy boots" I feel could work better as a permanent upgrade with limited rechargeable resource (think levitation from Undying). In a way, that's what they are already, assuming endless respawning supply. Except currently the player has to backtrack and the mapper has to account for infinity in all directions.
