This game was my fucking jam back in the late 00's and I'm pleasantly surprised I'm finding it again (ironic I'm finding it after the death of flash support but hey, I've got my methods :P)
Very simple mechanic and artwork but incredibly addictive, and a fantastic ost

This is a very nice game. It has a very nice story with very nice graphics. You should make a second game! I hope you have a great day Bye bye now! :)

Oh hey i finally found this again! this game'sonly problem is that the thrust gets stuck. otherwise this is the best game that i have played like this.

fun but hard.usually these style of games are done lazily,but you put some work into it :P

and the only thing that doesnt make any "scents" is your review new world,the game is fun but not easy,thats all there is to it

very adicting and very hard. but all in all a great game wish there were more simple and fun games like this.
