Hi there! Thank you for your feedback! We're working on improving the walljump mechanic. Feel welcome to replay our game again when we'll have an update, your progress should be saved to the latest checkpoint that you've reached :)
Do you perhaps remember at which part did the music overlap? Was it by any means the part with a very huge moving obstacle? Or did it happen around the level introducing spikes or nearby one of the three modules that you can obtain?
