Upgrade to Amount 1 / Health 1 / Armor 1 / Cooldown 2 / Growth 4
Go for Knifes => Blowtorch => Frying Pan => Onions
Run in a straight line, with Growth 4 you'll level up way faster than enemies. Get all upgrades and you can survive indefinitely. You can put more points on Health and Armor to be safer and to have to rely less on chickens.
You click on a thing, you have bonus for money/s and money/c. There's nothing more, no graphics, not even info of the price of upgrades. I'm sorry to be rough, but it's not even the basis of a game at this point, every single Idle game have those. I can't think of any reason for uploading such a "game". Please work on this way, way more, and deliver the game way it is done, not when you started working on it.
I do really want to like this game, because it has a ton of good ideas. But dev won't maintain it anymore and memory leak makes it unplayable. For future game devs: the more your game is complicated, the more your UI has to be polished. That was the thing this game was lacking, and it would probably have had a way better reception with that being changed.
