Hello!
It was nice overall. Grapple mechanics are nice and boss mechanics are well thought. The focus on platforming is a nice touch. At the same time, platforming mechanics need to be polished to fully enjoy the experience. In terms of level design, At times I felt like I was being funnelled with maybe too many one-way rooms, was it maybe just my impression?
Congratulations!
Cheers.
PS: try to find the sequence break in our game :D
