Oh nice, that is an interesting feature! I would imagine that it would make a lot of levels a lot easier. I may need to go back and check that out on a few levels.
And I was wondering if those levels had been added later. I figured I would give my feedback on the pacing :)
Oh cool! So for reference, it took me 605 tries on 10-6, and I beat it 59 times to finally get 57.756 seconds. Also interesting is that 10-5 actually took way more attempts (1120) with 3 successful tries for a time of 11.41, but I never felt very discouraged on that level. I think the main difference is that 10-6 is a full 60 second run while the others have you fail much faster. I want to add that the fact you jump up past all the text thanking the player for playing the game was a really neat design choice on that level.
Anyways, thanks for the reply with more info. I hope you continue to develop more games, as you seem to have a knack for making some fun ones!
