Nice gravity shooter concept, I haven't found any exploit other than waiting the enemies to line up and than swipe them out by mashing the fire button, I couldn't find any UI elements that tells you how many dashes you can perform.
I would also suggest adding more sound effects like splatting and screaming, that would also add a lot to the atmosphere. But I also feel that for how basic enemies are at the moment, designing more enemy variance should be the main focus at this stage, but I haven't played enough to see if more type of enemies could spawn from the ones that just chases you.
