simple but interesting. More robots or something else could add a lot to the game.

Simple but interesting idea ! It needs a little bit of polish, like adding sounds and a difficulty curve, but it's a nice little prototype. Good job =) !

Promising idea, maybe another mechanics or limitations would make it more interesting, like the robot turning on and off, things on the way forcing the robot to take different routes, etc.

Wished it had a little bit more of depth like multiple robots, a cooldown for placing the coin... this way it can be more challenging. Some sfx when placing the coin or the robot catchs it would be also great. All in all, good job.

Interesting idea for a mobile game. I could see it as like a time waster on the bus. However, I think there's a big issue with the coin collider. It seems way to big on the bottom. The robot won't even be close to it and it'll count and force a restart. I'd say look into that if you're continuing with this. 

I like the idea; however, I feel that you need to add a way that the game gets harder. As it is, I just kept placing coins in the corners opposite of each other. Maybe you could make the play have to juggle between several coins and have to pick them up instead of just clicking where they want them to go.
