A nice little cute quick puzzle game.
FYI, if you move fast enough, because of the discontinuous way it decides on your mouse cursor's position, you can tunnel through barriers. It's how I got the 2nd place score after playing this for probably half an hour total. I'm sure I could have easily lifted my score a bit higher than where I got it up to by revisiting some of the levels (especially a few of them that I left sub-optimal just because I was glad to be done with them), but I didn't think I could quite shave enough time off the various levels to get my score past 10k and to the first place slot without a LOT of pain and misery and suffering, so I'll graciously accept 2nd place on this one (but I'm still the best on Pause Ahead and no one's ever beating my speedrun on that). I did this with a frickin' TOUCHPAD and not a proper mouse after all so I think my performance is nothing to balk at.
So you might consider such things as that when making programming for things such as this in the future, because it makes the solutions for some of the puzzles a bit easy and cheesy, to win them drastically faster and in super-easy ways that you weren't intending. Call it cheating if you want, but I feel I operated within the rules. I just moved too quickly for it to detect that I passed through a red barrier, and if that's the way the game behaves, exploiting it is fair game IMHO. Naturally there was no way to make the blue thing move fast enough to pass through blue barriers, of course, so there were still some considerations to the strategy of the game that were like its original intent even when playing like this, but it's interesting how it actually makes each level a completely different sort of game when it is played in this way.
