Good effort!
Nothing new in the game but it all does work very well, it could be a more pleasant time killer with more polished graphs and a not so psychadelic and repetitive environment (it's alwyas the same wormhole but since the ships inside do change the landscape could as well) I did like that intro story you made and that quite humurous script (but you made it too long in level 2!). 7/10 and 4/5 yay! :)
P.S:This reminds me of the early nokia cellphone's game, the space shooter xD.
