2D Crypto Mining Tycoon Game

I’m planning a casual-idle tycoon experience built entirely around a Mining theme, with the core activity centred on Crypto rather than traditional gold, coal or gemstones. The gameplay loop must feel familiar to anyone who enjoys an “Idle Tycoon” style title yet offer enough depth to keep players engaged over longer sessions.

Core mechanics I need implemented:
• Resource collection – rigs generate crypto over time, with production speed affected by power, cooling and algorithm difficulty.
• Upgrades and enhancements – players reinvest earnings into better hardware, energy efficiency boosts and facility expansions that visibly change the mine’s appearance and stats.
• Trading mechanics – an in-game exchange lets players buy low, sell high and hedge risk, adding a light strategy layer without turning it into a full market simulator.

Deliverables:
1. A fully playable 2D vertical-slice (PC or mobile build) showcasing the above three systems working together.
2. Source project with clear comments and organised assets so further content can be added easily.
3. Simple UI art, placeholder sound and tutorial pop-ups sufficient for usability testing.

Acceptance criteria:
– Idle generation, upgrade purchasing and trading actions all update player balance in real time.
– Progress persists between sessions.
– Frame rate remains smooth on mid-range devices.

Feel free to use Unity 2D, Godot or any comparable engine you’re comfortable with; I’m interested in maintainable C#/GDScript code and clean scene organisation more than the specific tool. Please include a quick outline of your proposed workflow and timeline when you respond so I can gauge the best fit.
