I now realized that the update that will bring the improvement system to the game will be very large, and I decided to release it in parts so as not to keep you waiting for weeks. As soon as the first part of the update is ready, I will immediately upload it to the itch.io server.

Or is it better to wait and get a full update? If i knew..

So that you understand why it will take me so long to update this: In other similar games, you can constantly watch tier1 tier2 and so on, so, in order not to do the same, I will come up with a slightly different system. You will collect the necessary components to upgrade from enemy units and enemy buildings, then, for example, you want to improve the conveyor belt, you will improve it using these components and it will become the second level (tier 2, is that you?) the conveyor belt will not only change its characteristics speed, but also appearance. This is why it takes so long, I have to create a new look for every machine and conveyor belt for every upgrade.
