Thanks so much. Fantastic stuff ! Loved the "iceninexp was here".
I finished all levels, including the boulder chase one without needing to use the keyboard shortcut. If it had another second or 2 before the boulder came it would be a lot more doable but still challenging.
The piano puzzle could maybe use some visual cues (like the trumpet).
Platforming was sometimes a little floaty but never too frustrating.
Level 3 is there a way to get passed the spike-headed creatures without taking damage? That's when I started wondering if left-crtl was either not the correct key combo for the gun...then found the gun on a later level.
There's a lot of potential. As I mentioned in my first comment the diversity was probably the most pleasing thing, a little bit of everything and all the pieces worked together, nicely homogenous , which isn't a very common.
