I think the movement may be bugged. It stops moving after a moment even if I'm still holding the button, and freezes any time I attempt to shoot. Keep making games! You'll keep improving as time goes on!

I liked buying upgrades, I wish I could do more! After buying the two there wasn't much more to do. Since buying each had a huge effect, maybe they could be broken down into more upgrades with smaller effects each?

I'm not sure if there was input queuing (I would try to fire but not get it a little while after) but since timing is important maybe it's better if it didn't and just stopped me from firing if it wasn't ready.

Good job, keep at it!

You got my rating :)
