Ugh, the controls are so horrible. I let go of the right arrow, he keeps running for two seconds. This is inexcusable. Why? The sequel has the same problems.
Never Gonna Let You Down Badge (hard - 30 points)
You acquired this badge on Sep. 30, 2010.
....even though it give the date, I honestly have no idea when I did this, especially considering I don't have either of the medium badges. Maybe I just got lucky on one run?
The cheats are horrible, they're all just random-size one-use bombs (283625312 gives you the largest from what I can tell). This game doesn't explain what any of the weapons do, either.
I understand the hate of the last level, because it's one of those things where you know exactly what you have to do, and it's not hard in of itself, it just requires split-second timing. Nobody likes false difficulty like that.
It's the sign of a bad storyline when you beat the game without even having paid attention to the story because it's not entirely obvious you're being given vital storyline information. I assumed the rooms where there was not platforms were just a breather room, didn't even stop to read the information. You might want to consider restricting movement in those rooms until all information is given, forcing the player to read.
