I got to say the retro 80s music and the 8-bit pixel is a nice touch. I noticed there is no way to pause the game. Is it included? As for my feedback, does game included a variety of weapons upgrade and map, but if not the game may need it to enhance the gaming experience. Also, the game needs an inventory so that the player can look up the maps, weapons, and item acquire. My last suggestion is the game needs a setup for how many video-game lives the player has, 1-up item, save state within the level, continue and game over that leads to restarting the game that adds an engaging challenge to the game play. I hope this suggestion would help your game.
