Fun and simple top down shooter. I liked how the amount of sides an AI had, it cost that many lines. I also liked the simplicity of the visuals. I do have a couple bits of feedback:

• The SMG (I think that is what it was) didn't really do enough damage, especially for the range, and the sniper (I also think that is what is was) was outclassed by about everything due to the low rate of fire, and that it didn't do enough damage overall.
• The game did feel a bit too easy, I got to around wave 10 or 11 and I only had to occasionally grab some more lines to get more AI's, so a more exponential difficulty curve could probably benefit the game, and the player seems to gain power exponentially.

With those 2 issues aside, it was a fun game!

Love the title art, good gameplay, amazing work!

simple gameplay unique art and this become a great game jam game !

Really liked it! The visuals are simple but effective :)
After reading the comments I was able to play the downloadable version ^^ 

It was emotional pain

At first, I had friends. Very loyal friends.. but. ALL OF THEM, all of them were killed. Right there I made up my mind, I would destroy every single one of those red shapes. As I played I killed them and made new friends. But my new friends, they died too. I was feeling desperate, I started thinking I was in an infinite loop of losing my friends, making new friends and most painful of them all, losing them again. I stopped making friends. But I was alone. I felt sad. Then I realized I had 50 energy things. I made a lot of friends. An army of friends. But that boss. It had a shotgun. It killed my friends. No. I couldn't take it. I killed the boss. And continued playing. Until wave 25. There was another boss. I was alone and feeling sad. I was killing that boss too. Right when I was killing it, I realized. That boss, it HAD FRIENDS. I killed the boss. I killed it's friends, was I the bad guy. Was I the world's enemy. I made up my mind. I would save the world. By killing the biggest thread, myself. But there weren't any enemies. They weren't coming. And then I remembered. I remembered my first friends. The vow I made back then. TO KILL ALL OF THEM. I had done it. But I couldn't save the world. But, but do I need to save the world, No I wasn't trying to save the world from the beginning, I was trying to save my friends. Then I realized, I can have friends. I CAN. There aren't any enemies left. I made 2 friends. I only had 14 bars. So now I have 2 friends. 8 and 6. We will live together. FOR ETERNITY.

Amazing job, feels very polished and is a job well done. The shoot sounds were quite a bit louder than the chill music. (Good music) Very nice presentation and graphics. As others have mentioned, it wasn't very intuitive. Perhaps a tutorial? 

Those shotgun dudes are brutal

My record is 158! Is it good?
