really cool idea! i have a soft spot for big numbers with regards to space and time so this game was perfect for me. it took me a few tries but i did eventually make it to lightspeed (only took a few billion billion years) i appreciated the redshift effect at high speeds (is it redshift? i didn't take a level physics) which was cool! and the missiles were terrifyingly well made - those dastardly accurate ones kept hitting me just as i got a new personal record :( it was a really cool game though, i didn't know i needed more relativistic games in my life until now!
