Nice concept
Bringing back the good old arcade space gaming?
Kept me entertained for some time. Got bored after buying all the upgrades adn defeating the 3 bossing. Still got a missing achievement. I suspect it might be a hidden boss or maybe 100,000 scored? Stopped at 80k :P
Good game though. Explaining that bombs and lives are Not cumulative oppositely to power,etc would help though but that won't ruin the game, would it?
