A tick to easy
I first saw this game on another page and loved it, especially because one could repeat levels and make cash like that und upgrade ones ship to the maximum quite fast. At lvl 9 i had my ship allready fully upgraded so the last 4 levels where easy. As i read out of othere reviews, you want to make a second part, it would be nice to make the levels a bit harder and add more upgrades or upgrade the upgrades (hope you understend what i mean :-)). Ok, getting somthin to put the power up is surely not a bad thing to do, but not really that necessary. Yes, maybe if the game gets harder. Besides that you did a real fine job.
