Cost to upgrade 1 unit: 500
Gold gained by grinding the only level available that you can't beat: 75
This game gets way too boring way too quickly - you literally have no options left but to grind the same boring level.
It's kind of fun, but you end up not wanting to pick up any chests after getting the bow. The sword is weaker, and the axe basically means the game is over.
The torch mechanic was annoying. I'd disproved all theories and got the key to the power station but I had to play through the entire game again just to complete the last step.
I know right! That's a problem with the engine I'm using to make the game. I actually wrote a bug report to them hoping they can have that as an option to turn off!
For the time being you can leave the game running on it's own separate window. That should do the trick!
I was thinking about this problem during dev process, and it was not easy decision for me to allow creators to do that. Besides confusing with background, designers can choose any colors for scene elements, including invisible white on white background. but in the end, players vote and decide is track good or not. I also check statistic, how many players started playing track and how many of them actually finished it, based on this data I make decision to put it in career or not, and catalog tracks XP points also calculated based on that (this is automated process).
It's really nice but there are so many points where it's impossible to figure out what to do. I've had to look in the comments to figure out what I'm supposed to do multiple times because there isn't enough information in the game for you to be able to figure it out yourself.
