Great game, I especially love the details like how bullets flash on the bodies. For the next one consider making a level progression campaign like Metal Slug and online multiplayer.
Everyone! They've been working on the game for a long time, you can play the full competitive multiplayer alpha on steam. They're planning to add new weapons, a survival mode, a campaign, etc. Right now it's just mp with 1 weapon though
It costs $15 on steam
