but you should have a good reason for using launchpads if you use them, and you should try varying your propulsion methods more. The worst part about this is the launchpad chain at the left end. There is never a time where a launchpad chain is good. There sometimes is for launchpads, but not for launchpad chains.

i kno its frustrating when no1 comments/rates, so i thought i'd drop both. Its a decent start but you have 2 big issues

1. too man launchpads (especially the cluster; always avoid that)
2. the single rocket doesnt provide for very many close calls

i suggest either going back and adding more rockets, or, if you have the time, start with a new map, using trap door propulsion, thwumps, and slopes (tileset) to add movement, rather than flying around with so many launch pads
