Not too bad! Very simple ofcourse but I had fun playing it.
The ''tornado get big'' is a classic ofcourse and I always find them quite satisfying but they usually end with just getting so big you destroy everything, having to instead climb up the clouds was unexpected but actually a fun little twist! The platforming was a big hard but that only game it more charm I think, gave me getting over it vibes.
I was however able to climb steep walls like in the pic below, which I am not sure if it was intended or not :P
Overall, fun little game! Well done
