A challenging game, I'm too rusty to get past the third level! I really like the player sprite and there's a lot of enemy variation. I was a little confused by one of the possible door choices though - it said 'More speed but less speed' so I wasn't going to risk taking that one! The one where you get no bonus but only a drawback is cruel but it was balanced by having positive-only doors too. I was lucky enough to get the bonus health and two bullets upgrades with no drawbacks at one point.
