It was an incredible one to play. The game managed to include so many cool features -- the screen shakes on the right moments, laser-like shooting style, cool upgrades, cool enemies and the game-mechanics -- that were astounding and engaging to try out and to experience. Plus, the fact that this game was made in only ten days by a single developer really amazed me. Definitely 5 star, try-out game. The creator really knows a lot about video game.
