Definitely meets the requirements for metroidvania and explores some fresh core mechanics. My primary feedback is around game design:
1. Please add coyote time to the jumps. Falling off ledges due to jumping one frame too late is a curse in platforming.
2. The doors looked too much like walls and the spikes did too. Consider making the spikes way more menacing so the player doesn't have to look so hard to spot them. Same for the doors, make them stand out from the default wall color.
Other than those things, I enjoyed playing. Thanks for sharing!
