Such a beautifully made game, great job to you and your team. The mini-games and overall game feel are excellent, and tying the player's speed and health to the timer is a neat concept.
Though the speed decrease feels more like a frustrating penalty rather than an engaging mechanic. I know doing minigames restores your time/health/speed, but if you drop too low, it creates a "death spiral". By the time you hit the last 10 seconds, you are so slow that if you aren't already right next to a minigame, you simply can't move to one. It basically means the timer effectively ends at 10 seconds, not 0.
I also encountered a bug during the Rat King fight: there was no debris left during the cog cleanup minigame, but the minigame didn't end so I got stuck. next time I did not encounter it.
Also sometimes I just got stuck on the level geometry, maybe the top down movement needs a bit of polish.
Nonetheless, amazing job, pulling a game this beautiful requires a lot of coordination with that team size, I really enjoyed the game and finished it, really great work overall.
