Lovely tower defense game. I liked how the towers sometimes acted independently, not always targeting the one in front. Also neat path finding

The game is entertaining, I played until round 30, the gameplay is kept simple, fast and challenging.

I think it has a lot of potential, thinking outside of a jam, if more things are added like an upgrade system for example.

 I agree about adding a little variety to enemy and certain benefits for the different colors. Nice entry!

I really liked the game.

Tried to force them go my way but it keeps finding a better path :)

You can try to add some bg graphics, music and sfx and game will definitely look better that way!

Good job!

I liked the ability of being able to place towers wherever we want, I just feel like it lacks some variety to make a good decision in placement. Like "This color is better at close range" or "This color attacks slower but does more damage." would go a long way in making this game better.
Also if you're going with the printer color theme, on idea for upgrades could be combining colors together to create a new tower with a different color.
