I really enjoyed this game. I had to get used to the "full speed is bad" mentalism, but after switching to fine adjusting my speed the game was fun. The later levels are really challenging, especially because some of the planets have a wrong collider (you die without touching the surface visualy).
The sound got a little annoying after some time of playing, but it's ok.
Things you could improve:
- Increase turn speed of rocket a little bit (but the game was quite ok with the current turn speed)
- only show the engine animation when the engine is really on
But overall, this was one of the better games I played so far.
I hope you take your time to play and rate my game too.
