Hey, congratulations to you and the team! This was a ton of fun! And a particular shout-out to how well you balanced the difficulty. Every stage felt very well crafted, the progression of skills & tests was great, and the controls were tight. When I died, it never felt like the game's fault, which is a great sign of a fair challenge.
That last room was a killer, too! But 355 seconds and 15 deaths later, I'm certainly looking for more. The only thing I'd suggest is looking at the separation between platforms and background; the grey-on-grey was tough sometimes, especially when you're concentrating - I was surprised to hit a few walls.
Excellent job to you all!
