Nice game, cool concept! Clean and crispy vector art! 

I playtested for a little bit, the game works and runs great, I'm only a little pedantic when playtesting games (I playtest games as I do for mine that now has a long list of known issues XD) this is what I noticed (apart from that 8 point goal stuff, maybe you already also noticed these): 

1. in the tutorial section: there is "poin" instead of "point"
2. I would normalize the speed of the diagonal movement (diagonal movement is faster than horizontal-vertical one, I suspect you add two movements without normalizing the resulting vector)
3. the player flickers a little bit when it reaches max speed
4.  approach the crystals on the bottom from the top (ending near the bottom border between two crystals, and to work you need to go down with a little bit of the player collision box intersecting a side of the crystal) and then try to move left and right: that movement is restricted  (seem by collision boxes of the crystal )
5. Sometimes I got a point (and a crystal started shooting) but I don't know why (doing nothing), it happened with bottom crystals while I was testing point 3. (maybe an enemy spawned inside a crystal?)

Anyways, great job!

If you add some sound effects it could become way better!!!

I had a lot of fun playing this!

More juice, feedback and sound effects would have made this even more incredible.

Great job!

Cool art, concept is good. Cute graphics! Good job

I think this concept has potential, like you could make a bigger level, a street maybe?, and give the player more weapons etc idk. I like the graphics and the physics.

Really cool art, I like how the enemies change colour when you attack them! Good game!

good game, but the music got annoying FAST.

Oh this took me a few trys to figure out the controls and the best way to do things. I really wish I could see the whole game play area on one screen, but over all a solid fun game. 

I find myself coming back alot to play again but once you have a strategy down you can't really lose, Gameplay is solid but simplistic and the enemy's can easily block each other if your slapping them away. I also don't see how this connects to the theme too much. Neat idea though.

The concept is really good! I only got one issue, the difficulty doesn't really adds up, maybe you could make turrets shoot faster the more you go on with the levels!
