Finally won a game! Aylon Cruiser, which definitely feels like it's stronger than the others - not sure if it really is, or if it just suits my playstyle better, but 45 shield on start is pretty useful.
I also got super lucky with an early +1 energy equipment and a drone dispenser for constant HP regen halfway through the second area.
I'm not confident in my current assessment of the game, but it feels like RNG can win or lose the game for you. I'm not a big fan of reliance on the lucky availability of the right cards being necessary to win, but I enjoy the gameplay enough to play even if I'm right in feeling like that's how it works. And as noted, I don't have enough playtime to be sure the game is reliant on RNG and not consistently winnable regardless of the cards you draw.
