This was fun !
I really like the tiny sprites they really have a style that feel authentic to what could have come out on an amtrad or comodore back in the day and that quality doubles for the gameplay with the fact you made it in an engine ( don't know how these retro computer style things could be classed like :p ) with i suppose quite some drastic limitations.
I also liked the use of the theme where your weapon auto switches every 10 seconds
shame you didn't have time for sound :( but hey time in jams flies and i can understand that
had a good time and this made me nostalgic for the old amstrad days :)
