The game looks good and the sound effects were nice, but when I got the controls worked out it became too easy. Impressive that you made it in Scratch though.

Small detail: there seemed to be blobs stuck in the corners of my screen which looked a bit odd.

Artwork, Sound is good but the game idea is so basic and common, There is a thing in game that you can hold the left buttton of mouse and move cursor around your player in circular path this create an un breakable sheild around player which make game so much easy because enemy dies immediately on touching boomerang. You can disable this feature and only allow fire on click and you have to release button and press again to fire Or there is an other way that you can give enemy health bar which give some time to them to reach player even spamming around player in circular way. You also should add more feature like some coin system to buy some power our stuff like that...

overall view: This game  Sound design is good, Artwork is also good. But shooting system make this game boring. Game idea is also so common and simple.

Cool idea to use a boomerang! 

it took me to 25 500 till I realized you can shoot the boomerang , the player get stuck on the left side from some reason , otherwise  very nice game.

Pretty fun for only taking you 3 hours to put together! Loved the art here, tho would love to see more enemy variety or boomerang effects. Either way, a fun little base for a boomerang Vampire-Survivors-like!
