Thank you so much for playing!
I was actually scared that level 5 might be too hard. I hope it wasn't frustrating.
I thought the untouchable ambulance on lvl 4 would feel like more of a challenge because the easiest strat for the first levels usually involves moving flush to the top of the cars. If I could change it I would probably make the walls on that level untouchable too, to require more precise motion.
Anyway, it was a fun quick project and I'm really happy you enjoyed it! :D
