Pls add feature on UPGRADE tab showing for each mine/smelt/forge/enchant action how many levels of upgrade is required to double current performance. Also ACHIEVMENT tab is missing any INSANE price score, hope it will change :)
First of all, nice game, I like it. I'm not so sure how most of idle games works but I can't get into any highscores list. Is it because ppl who started playing some time ago and abandoned have their score updating no matter what? Did you consider any mechanics which stops updating when player only reloads webpage not doing anything at all?
BTW. Considering UNITY features I bet this is done prolly during first steps, but is really nice. Did you accidentally have any blog about developing games under UNITY WP?
