Thanks for playing and for your feedback! I think the movement could be adjusted easily, I have player speed, velocity x/y and max velocity x/y variables that can be tweaked. Are you thinking it needs a little more acceleration speed so you can react more quickly?
This is one challenge I found from the 64x64 size: how fast should the player object move so that it doesn't zip across the screen. If this wasn't a game jam entry and I had more time I would have liked to have asked people to do playtesting and tweaked these values before submission but such is the nature of a game jam. :)
