Uchuu no Kishi: Tekkaman Blade

Tekkaman Blade is a 2D side-scrolling platform game where the player controls a mech and must find the exit to each level. The mech only has one melee weapon, but it can also use a special grappling hook, like in Ninja Gaiden Shadow, which is necessary to go through the levels. After the platforming part of the levels, the mech fights against a boss.
