Great Concept
This is a humorous take on the upgrading element of games, but more importantly it is a very well-executed shooter. The gameplay is very smooth and easy to learn, making it easy to focus on logistics. The speed booster is fairly unnecessary since flicking the spaceship left and right keeps most of the field enfilade. Still, the difficulty curve matches the availability of upgrades very well, making it challenging but not frustrating. The graphics and animation are both very fitting. Even the 8-bit style is fun and functional. Perhaps future versions could incorporate an upgrade allowing the player to toggle graphic styles. My only complaint is that after level 20 has been beaten and the ship is fully upgraded, it ceases to be much of a challenge. More levels or different challenges would be a great addition.
