Budget: 27000 UAH Deadline: 14 days
Good day, Volodymyr.
What exactly do you want from this project?
If it's just an idea or a prototype for a coursework, then 2 weeks is fine.
But if it's a full-fledged game that will compete with other games in this sector, then you will need at least 3-6 months, or maybe more.
Also, the question is why specifically Kotlin?
For good visualization, Unity or another game engine would be more suitable, not a language for applications.
Do you have a complete Technical Specification (TS) for your game? Or does it also need to be written?
Do you have graphic elements for the game?
Do you have visual effects for the weapons?
The list can be continued further...
