Hello again.
I have made some changes to the mechanics, taking into account your feedback.
1- Sprites of the player and miners are smaller.
2- I have limited the movements of the player and enemies, so that they move more like in a rogue game. Now there are no diagonal movements.
3- Enemies disappear when you touch them, limiting the total damage. Now it is also easier to run away from them.
4- EMPS are easier to use. There is no loading time.
5- The miners counter is fixed, so the demo has the right gameplay time.
