Like the look of the graphics, are ship & enemies as big ingame? think it would interest me more if it was just scaled down a little but am no expert

- I didn't find it clear at all that "X" activates the powerup, and that you see through the glow on the top bar what is the current powerup stage; in the controls menu, it doesn't clearly say X in the same way it says SPACE and such. - for pause toggle, ESC is a good key (which does nothing); you have a super tiny hidden mouse-clickable pause button in the top right of the UI....
