Obnoxious level design, unbalanced difficulty settings (normal is a cakewalk, hard is a frustrating mess), bosses and even popcorn enemies are massive bullet sponges, nauseating top-down stages, excessive gimmicks, and somehow the weapon swap bug was never caught in testing. One of the few 2D Contras that missed the mark.

Broken enemy spawns, awful hitboxes, frustrating controls, annoying upgrade system, pushover bosses. The art design is pretty nice, but clearly all the focus was put there instead of making a fun and competent game.

Enemies have shitloads of HP and just spawn endlessly right in front of you. Controls are very stiff. Jump is very awkward. Visibility is extremely poor with your clones, the visual effects, and the enemies that look similar to you (and your clones).

I just don't really get the appeal here.
