Unforgiving game at first run - i didn't even noticed first two signs with tips and rushed down with panic :D Also sometimes, when cart gain some speed it's almost impossible to click on signs - sometimes even cursor didn't turn green when i was near signs.
Anyway, what was your goal? It's isn't obvious for me, and you didn't write it in description.
Thanks for the feedback !
Because of the lack of time it was hard to fine tune some things, like good positionning of signs and an easier way to launch the hook at high speed.
And was the cursor grey when you tried to launch the hook ? Because if so, it means your hook was broken by an earlier launch ;)
The goal is to reach the finish line as fast as possible while keeping most of your gold. Although we displayed the gold, we didn't have time to display the time. A new version of the game has it with leaderboards, and we intend to polish it after the jam and upload new versions
Hopefully you'll be able to play it and enjoy it even more :)
imho - main problem of your game is that signs blends with surrounding - highlight it with color (or make it reflect sunlight like modern road signs) - hopefully Mark already explained that.
Also, as Mark said, theme was "GENRE without MECHANIC", and as i said you haven't mentioned what is your genre and what mechanic you had thrown away. Maybe it's just me, but i didn't understand what you have said with your game.
Thanks!
In fact, I was checking this evening and many of our signs finished in some of the last 3D Assets so, yeah it's too hard!
I'm balancing it right now. We also have apparently an issue in the function that compute the minecart speed: the gold weight is influencing in a strange way. We'll surely fix that ^^
Here's a screenshot of the start we have right now : 
Thanks for testing and for your comment! :)
