great fun
first of all, there is power ups, just get a bit further than level 2. dont review low and rate low because you have a rubbish computer, this is a good game, with multiple enemies which are all cool. Although i cant get to the end, the "boss" levels with special power ups such as rapid fire or quick bomb are great, and require great co-ordination and focus, i love it. How do you come up with so many different enemies? i also liked the different little shooters in the middle, which was a small extra bit of variation. :D
