I think a visual indicator of the player taking damage would be helpful. I was on wave 8 with fully stacked defences and died to an ant that somehow killed me through my mech as I was repairing it.

Thanks for playing the game.
The player sprite turns red when hit but there is no sound effects implemented for it. I think there is a bug where the player changes animation when getting hit and it makes the red color.
The ant has a very big attack area. We wanted to avoid a scenario where player is repairing the mech and ant damage is not enough to kill it so we went this way. Looking back on it, I think we should have done telegraphed it better.
