nice

not bad but a little bit boring

Very nice. Many of the levels require timing and patience.
Level 20 is crazy hard though.
My trick is to use one of the characters as bait (using the wall bounce aspect for luring the red death guys to a corner while holding one arrow ready for moving to the escape path), one the 2 red deaths are distracted, I remove one arrow off the initial path and feed the other 5 off around the top corner looping to the exit.
The trick is in timing and planning. You can beat the last level without a freeze if you want, but it is still tricky.

Cool game^^

pretty cool. I thought it moved a bit slow, however. I understand that there is an issue with high speeds when the movement patterns become more complex, but you could get around this by adding either a speed up button or maybe a slow-medium-fast thingy in the corner.

Other than that, my only issue was with how u had to drag the units to the starting points. perhaps consider allowing to just click the arrow, or to click the unit and then the arrow, to start them on their path. Cool music, too. Let me know if you need any music for games, i've got TONS of chiptuney stuff as well as hip hop/trap/etc
