Welcome to Survival!
This is not a super high effort game, it is just something that I threw together.
How to Play
Right Arrow/D : Move Right
Left Arrow/A : Move Left
Q: Start Game
The Objective of this game is to survive all 5 rounds! If you get hit once, you will lose! Move around and avoid getting hit! Every wave the enemies will multiply, getting faster, and the boundaries will shrink as well! On Wave 4, enemies will spawn closer to the player, and Wave 5 they spawn at y 0, so watch out!
Also You should full-screen the window that you play in!
I did not find any bugs, except for a minor one which has to do with boundary manipulation
Nice job, maybe try different color circles, also you can add different shapes, like triangles that can be "missiles"; instead of randomly falling, they will keep on following you for a short period of time. You should also be possible to move up and down, thus being able to move around from missiles ;)
