Great work on the polish and having everything in a clean and playable state. The concept is clever. I think it would help to be a little more zoomed out/have less UI on the screen at the start so you can do some strategic planning. I couldn't always see all the objects in the room so I had to use some trial and error to clear rooms, but I think it would have been even more rewarding if I could have fully planned out my strategy before clicking go. 

Nice art, gameplay was cool! 

Only problem are the WASD controls, we don't all have a Qwerty keyboard so it's better to use or add the arrows as controllers too

I like the idea, but I feel like the game is too hard? I think it could be made more enjoyable by increasing the player speed or by extending game area. I died at least 10 times in a row trying to figure out the player movement.

Also I am not sure if this is intentional or not but when the "Choose!" menu shows up, the player isn't actually required to choose a color since shooting is still allowed and when the current color is white, it is actually better to not choose anything. Levels 2 and 4 can be beaten this way by shooting white bullets to both enemies.

I really like the look and concept of your game however, it's incredibly difficult to get started. The player is shot before they even have time to process what's happening or how the game is being played.  I really like how the player needs to attack with the enemy's complementary color! I also really like the look and polish of the game, just the level design needs some work. 

I can't play the game on Browser:(
