I like how the story drives the gameplay forward. I was confused at first when I watched a little bit of your devlog video and then started my play through... I couldn't jump! After sorting that out a few minutes later it was all good.
I liked that you implemented a variable jump for your player character, but the overall feel of the platforming and player movement was a bit off for me. Navigating up from the tunnels felt slower than maybe it should have because of the combination of speed and jumping dynamics.
Thanks for making and sharing your game!
