---Achievements---
The game will be released with 15+ achievements. That leaves room for at least 5-10 future achievements.
I'm also adding a hidden option to reset Steam achievements and/or nonSteam variables. More info later or upon demand.
---Trading Cards---
Very happy to make these once Steam notifies me I've sold enough copies to be allowed to participate in this aspect of development.
---Updates---
If I'm surprised by sales, I'll start checking with fans concerning possible updates to the game. Assuming sales are low, I won't have enough incentive to update the game regularly.
