To get the 100 stars achievment, here are a couple tips. Of course you will need the top type of paper plane and engine, or just try and max everything out anyways. If you have fast eye-sight, just get to 50m in altitude and save your fuel to guide your plane into the cluster of stars. And to add to this, keep tilting your plane a bit upwards to stall it.. only if you have quick fingers, spam the arrows and space to unstall and get a boost. If not, just use the first rule and use as little boost as possible. Rate this comment up to preserve its use :]
