Calvin
In this game, players control Calvin, whose task is to rid the caverns of
various enemies including flying robot hats and green dinosaurs. Players start
off wearing a sleeveless blue suit which has no weapons, leaving them with no
choice but to jump over these enemies. However, there are two types of pads
that can be stepped on to give you different suits, and these suits give you
weapons which can be used to destroy the enemies with.
When killed, most of the dinosaurs will drop a flashing P icon, and when it is
collected, the suit will flash for a few seconds and the player can use a
pulse rifle to destroy everything in their path. Vines and jump pads can be
used to reach higher platforms. Regardless of what suit the player is wearing,
it will change back to blue if they take enough hits. At the end of each
cavern is a boss that needs to be defeated for Calvin to proceed to the next
cavern.
