Blade Buster is a shoot'em up homebrew game released in 2010 by High Level Challenge. In this game, you set the timer to either 2 minutes or 5 minutes, and your goal is to score as many points as possible. The game features a variety of weapon upgrades and huge bosses, just like how you would expect from outer space games!
thegugafá plays the 5 minutes mode and finishes the game in only 4 minutes and 24 seconds.
