Nice take on the classic! I like the unlockable difficulty options and online high scores, they add a lot of replayability.
To nitpick, I think the controls could be improved a bit. Currently, vertical movement is prioritized over horizontal movement, so pressing up while holding left makes you move up — this makes sense and feels pretty nice. However, the opposite is not true — pressing left while holding up does not make you move left. I think the last pressed input should be prioritized, and if the last pressed input is released it should fall back to the previous input. I hope that all makes sense. It just feels really inconsistent, and actually caused me a handful of deaths.
Other than that, it’s very solid and pretty addictive. I got #2 with 14k points at the moment. Some villain beat me with a score of almost 69k while I was writing this, that’s wild.
