Thank you for the feedback! it means a lot. I had a lot more ideas but couldn't make it in time so I let it go. After the jam I will update it for sure. There is no goal right now, you are right. I am planing to expand the map size when play reaches some levels and I will add map size based enemies. We will start small but we will go way much bigger. Currently game is so easy every run is impossible to lose. I will make sure it doesn't go infinite so player will eventually lose and leaderboard will mean something. 

Thank you so much! I’m really glad you liked it. Your game might actually be one of the first ones I played in this jam! The shaders in your game look amazing and have a lot of potential. While playing, I thought to myself: it would be 10x better with sound; the lack of audio feels like the biggest missing piece.

Other than that, it would be amazing if you informed the player at the end of each wave and offered 3 upgrade choices. For example, a turret that shoots at balls, or a passive skill that expands our area, etc. I think these would make the game so much better. Having a brief red vignette effect on the screen, along with a subtle screenshake and sound effect whenever the player takes damage would be awesome too. Also, as waves progress, increasing the enemy count more, increasing the enemy health, and adding different enemy types, combined with a leaderboard would really take the experience to the next level!
