yes, the canons do have the same range and instant-kill, but if ur the kinda guy who doesnt care about protecting ur canons, then u use the more advanced 1s (they have more health)
its surprising that after several tries on the levels u thought were impossible, u could get them. its a very good game, but it would be cool if there were some power-ups, obviously timed, on different platforms so u could jump to get them. 5/5 ;)
