Tried it with the new controls and it's much better when it comes to that.
What follows is entirely subjective, just a warning:
I finished the first level, almost finished the 2nd one, got bored and closed the game. Everything is slow - your movement, the progress (first level seems like a training level, yet you need to pick up whole 50 of those energy orbs). The environment is very bland - maybe there's more later, but the beginning doesn't fill one with hope.
It used to be that you bought a tape, a cartridge, a diskette with a game, went home, installed it and then, since this was your one game for a while you gave it a real chance and, quite likely, excuse a great many shortcomings. Me and a pal spent probably weeks on beating Battletoads and Double Dragon on the NES - playing again and again and again to get through to the end. But today it's 2015 and one can get a dozen games a day, all for free so a game better wow the player right from the start and just escalate from there. Not necessarily with mad action, but with something - be it art, music or interesting gameplay.
In this sector I'd say Insanely Twisted Shadow Planet is the one to beat - an absolutely amazing game - it opens with a bang and only gets better. The environments while simple silhouettes are amazing, full of life and very nice to look at. There's constant gameplay evolution - it's basically a Metroidvania with a little flying saucer.
Not saying you need to be like it, but it has plenty of lessons to teach about being a cool space game.
