Playing on a laptop and I wish I could rebind keys to something I'm more comfortable with than default.
Also wishing that reset started the level right away instead of kicking you to level selection and that there was a 5 or so seconds grace period where time doesn't start running if no input is given.
Got 47 seconds on level 1, only thing I dislike is that it's hard to rocket jump from walls since your guy snaps to walls and aims at the opposite direction if you're too close.
Edit: Wait this is DD 66's page...
