I really appreciated the concept, and I enjoyed the few levels that there were. A few thoughts/ideas:
I wasn't a huge fan of the single button on the level where you had 3 states to toggle between. If you wanted to take this beyond the scope of the original one button jam, I think that up and down could make a lot more sense.
If you controlled a second set of values with a second button/axis, I could see the puzzles being quite complex & fun.
I did hit a bug on the flappy level. Not sure what happened, but I hit a spike and instead of resetting, the game just stopped. Screenshot below.
