Gunmetal Arcadia

It's a short little game with fluid controls, endearing graphics, a solid OST, sufficient lore for your retro action-platformer sort of game, multiple player characters that provide enough variety in the early game to keep things interesting, lots of items to collect and experiment with over runs, challenging but fair difficulty, and high replayability.

There are a decent variety of weapons and subweapons/items as well as different playable characters which keeps it interesting.

The graphics, music, and sound would be fitting for an NES period game.

I never start my review of a game discussing the sound, but I have to for this one, because for me the soundtrack is the one that hook me first instantly when I start this game up.
