Replaying this again in 2024, still quite fun. User created levels can be hit or miss in terms of readability. Finally beat Clubstep, and lots of new additions and currencies, but no IAPs which is a blessing.

Finally beat Theory of Everything 2 after a two week on off grind! Took a break after unlocking the three locks but still fun. Just Deadlocked left..

A classic, really came into its own after The Impossible Game even though I only saw it as a knockoff originally. The levels after the 10th or so got brutally difficult, but all the user created ones were cool.
