Agree, I want to polish it, since I had to cut many things out of the initial design/idea to have a playable game.
It was supposed to have stages, and get the sunglasses after completing them. Also the ability to combine glasses at some point, I wanted glasses to use energy when using them, so you couldn't abuse them, but I'm still thinking on it. And when combining the three, you get these golden glasses and see all the enemies but with lower alpha, lets say 30%, and some power-up as well (that's why the weird buttons).
Enemies were added the last day of the jam hahah, so I only had time to tune it to be somewhat challenging and not impossible to win.
So thanks for your feedback! Glad you liked the protagonist design.
