Fired Up is great first product by Studio Outfall, a student team at the Los Angeles Film School. I feel honored to have been an early playtester, and to have been able to watch the production effort. While a few rough spots remain, it's got good art, good music, and fun opportunities for blowing stuff up. Give it a try!
P.S. The asteroid boss is brutally hard, but possible with the secret powers of the 'L' key.
