It's kinda fun, but you shouldn't make enemies move randomly in this sort of game
It feels unfair when enemies have no pattern and starts to aggravate people

it's ok, but it's extremely annoying that the enemies move on a grid and the stages are gridded but for some unholy reason, you don't move on a grid.
keep it consistent

Using the arrow keys to attack causes the page to shift up and down. Also, sometimes enemies/the player could become misaligned on the grid, causing a death if you got within a block that would normally have been perfectly safe. Good art and music though

EDIT: control change really made the game better. Updating from 2 to 4 stars.
