Hi!
Thanks for trying the game and providing feedback. Regarding Steam release - I think closer to Autumn. Still a lot of work should be done. I plan to do few more updates to itch demo, including some new content, so there still will be some new content available soon.
Regarding your suggestion for resources display and speedrun milestones - I am working on it, I think it will be included in next update.
Regarding skills - I will work on it.
Thanks again for playing and providing feedback!
