Essentially, everything ecaroh said is spot on.  Needs a lot of work, but not a bad start.

At least he was able to navigate the coffin.  It never showed up on my screen, no matter what I did.  Also, there was a floating feather on the top-right corner of my screen the entire time.  Thank you to Cider for pointing out a trick to getting it on the screen.  I was finally able to navigate around to the perfect spot to collect my Pacman pills.  :)

Cool start to a space shooter.. or maybe just a space drifter? Good work on the 8-directional sprite rotation! Once i got used to the movement sensitivity I was able to actually steer it and collect some points with some control.

Since it's just a demo right now, I'd recommend setting a few parameters for the player like minimum/maximum positions so it's not possible to drift off screen at least. Then it's like a sandbox to learn the controls without accidentally going out of bounds as you learn them.

I'm really curious where you can take this idea further. The "space coffin" premise is really intriguing and creative. I don't think it's ever been done before!

Btw if you hold R down, you can get a cool effect with a wave of points!

Tip for other players: the itch.io window is small at least on my browser, so you have to use a bit of thrust and wait a few seconds, then the ship should enter the screen. You can then fly around on screen. Good effort, I hope to see more creations
