Simple but still fun. Glad the option to hold the key was implemented, saves me from arthurites.
I also love the tick indicator showing how many seconds before the count is down.
My only complaint was that, to my knowledge on level 3 you have to kill the enemies to complete the level but there very tedious and hard to kill. But hey maybe skill issue ¯\_(ツ)_/¯.
Still great game though :)
