Thanks for the game!
I liked how you worked with color and shape to communicate all the information without visual clutter. The 'grappling hook' mechanic was interesting to play with, although it led to some glitchy situations sometimes. It's interesting how the game taught me to play itself through interactions with the environment as new abilities expanded my possibility of space significantly. Also, I think the lighting effect was really great at directing attention to significant objects and room exits.
With that said, I did felt lost from time to time, unable to cohere a mental map of the game world (the space was too abstract!) and understand where I have to go to move forward. Also, it wasn't always clear if rays of light show you direction to the next room or are they just highlighting an object. Eventually, I got stuck and unable to finish the game.
Nevertheless, it was a nice experience!
