Fun game.

The only issue I have is the fact that it's difficult to see behind buildings. You used factorio as an example but I think the camera angle in factorio is higher so it's easy to see everything on the screen.

Even when you make the building transparent, I have a hard time knowing the direction of the conveyor belt.

And I had one map where I wasted time searching for the metal nodes, they were all at the bottom, hidden by the forest. I only found out because I clicked everywere with the gold mine.

First of all, of course the story is awesome. I totally understand the alchemists addiction :D

I really like the artstyle. Its very smooth and the Ui is nice.

I normally dont play factory building games, but the Tutorial explained it well on how this game works :D

The Gameloop after it is nice too. The waiting after the tutorial/ in the battle for the exit felt like it could have been shorter tho.

At first i didnt understand that the alchemist makes the shadow guys with the gold and potion and that thats the point of his factory building plan. (Atleast i think it is?) 

I think it might be nice to explain how the alchemist plan works in the beginning too. Maybe only a sentence so the Player directly knows why and what he is building factories for.

But in general its a great game :D

A lot of the interaction feedback for this is quite good, with appropriate highlighting and SFX. The exception would be the building buttons in the resource gathering screen. Filled the quota almost 2 times, 40 zombies got nuked by tazers.

There’s no volume slider to adjust sounds or musics, which meant that the music drowned out quite a few of the sounds. It’s also unclear how much you should save up before you BATTLE at first, but thankfully the initial penalties for doing so aren’t s dire.. but waiting for the EXIT button no a timer is annoying. The window scaling issue also appears to be affecting cursor position - I noticed that the cursor was becoming increasingly desynced with the mouse (lagging behind) the higher x and y become. The click point is still where the in game cursor is, but it makes selecting buildings and units to place difficult.
