Sorry you had issues with the difficulty. We’re working on that in our post jam update.
Something we should have mentioned before is that you can get access to all levels right from the beginning so you can skip a level if you want.
To access all levels: Click the title 10 times in under 10 seconds. You’ll hear a chime and the Levels menu option will appear (if it wasn’t there already). Go to the Levels menu and you can start any of the 10 current levels.
Thanks for your feedback!
