i kind of think this is true of almost every game, but could benefit from more stats. stuff like accuracy or % of enemies killed.
and obvious stuff like levels and so on. starts could be squares or kind of glinty so they can be distinguished more easily from enemy fire.
i didn't have much of any problems with bugginess affecting gameplay. you have to click a couple of times sometimes on an item or the character won't go all the way to the table sometimes, but it doesn't impair gameplay much. the movement being smoothed out would really help the game though.
decent enough game for what it's trying to do.
needs either more levels or a game over screen because after like level 7 or whatever clicking just increases the level number and i'm just looking at the same screen. passable breakout clone otherwise, like the collapsible hives
