Great game, but it needs 3 main things.
1. Trading beyond 9999 per higher resource. This makes the very, very late game super slow.
2. Fix the leaderboards. Currently, the Manual Score and Trading Score leaderboards are fine, but the Auto Score is actually your Total Score, and the Score leaderboard, which i assume was supposed to be total score, is broken. This means that there is no working board for Auto Score. Please fix this!
3. Add more upgrades, resources, and polish the game a bit. It still has some minor graphical issues.
