I agree with you there is little room for improvement on the times it is something i want to address, I am considering making the movement more of a hold down to go that direction instead of the constant having to click to move a block. I will be changing the timing on this level i think its 45 seconds the others are 55 seconds to 60 seconds. My idea is that you would optimizing order of things you do it in. I think when I've played level 3 I've done it with 0.5 to 1 second less so it is a little tight to do it.

At first I thought that holding down option/more live action for the movement would solve the problem but there is another thing you could do. The problem is that the mechanics butt heads with eachother. The current movement is fine but it reflects something more turn based. It clashes with a time limit and will make it a hard thing to balance properly in the long run. My suggestion is either go with A) turn based movement with a certain limit of turns per level or B) live-action movement with a time limit. I hope this helps but its just a suggestion. It's your game.
