Amazing.

Very cool and addictive game (even though the plumber sometimes "stomps" on you while he's moving upwards)

The music fits well, and I really liked the fact there are different enemies you can play with, each one with their unique abilities.

Nice work, this stalker plumber needs to be stopped!

The game is kinda fun but it's kinda glitchy too. :|

The ball often gets stuck between the pink blocks, because they are not always broken when hit by the ball. Sometimes it even gets stuck in the game's "ceiling", which makes it impossible to win unless you refresh the page and try to play again.

Also, try to work a little more on the game's physics (for example. change the ball direction based on where the ball hits the player, and not randomly), visuals and maybe add some sound effects.

It has a good music and it's easy to control, though.

Nice music! It reminds me of Megaman.
