Good job with your submission! The intro is too wordy, I'm interested in the story but the faster you get to the game the better, maybe explain the main character's backstory as you go along, maybe start in the tunnels and the player finds out why over time. The fog effect is great. The controls could be better, for example, if you just have power A and power B and be allowed to press both together, you can get rid of the third option, and no matter what powers A and B are, you can combine them for interesting emergent gameplay. The game is too hard. The difficulty needs to ramp up way slower, for example, introduce one thing at a time, and make it easy to get through at first, then make harder over time. Room three is extremely brutal. Either put in checkpoints, or save collectibles when you die. Having to start all over AND get the double jump scroll every time was very tedious, and I never got past the double jump room. With some tweaking you could have a really excellent game here. Great work!
