I find it pretty neat. The overall structure and gameplay of the map is pretty cool.

A few pointers:

One, try using less enemies while keeping the excitement. Instead of five gausses, try using three gausses that cover more area.

Two, no trap doors that block the exit. Nobody likes a trial and error map. Meaning, nobody want to start the map over because of a hidden trap door.

Three, more push. Push is what drives the player to inish the map. Maps with a lot of push are relatively more exciting.

Keep it up, you certainly have potential.

It could totally use a rocket, though. Anyway, favorited. Good job. You're totally improving.

To be nice.

99% of good maps take more than 3 minutes to make.
Put more time and effort into your maps from now on.
