Video Commentary:

It's an interesting idea for a reaction time kind of game but the way to start and finish the shape is not the most intuitive. Maybe click on the first, drag trough the shape and release at the end would make the game faster and more natural. That way it would also be possible to play in mobile browsers. 

also, make the bug a feature! Two shapes? well, draw them both! (the small needs to be in front always)

Keep working!

Hey! I wanted to check the concept but nothing happen when click only some squares appear and dissappear. 

A bit confusing, some visual indication that you've set a start point would probably help. And right now it seems like it's all different size squares, I think the gameplay would lend itself better to matching shapes, rather than sizes.

This is an interesting concept! However it took me 3.5 seconds to draw 1 line haha, I think that should be increased a little since the drawing mechanic is quite difficult.

the controlling feels very weird. i prefer press and drag, with visual feedback when dragging.

Needs a little bit more polish but still kinda cool. Not bad!

Besides the two shapes bug I think a countdown of the time left to draw the shape would help, as of now I'm not sure when the 3.5 seconds start ticking.

I would also add some kind of audio effect when you click on a node with the left button and also a visual cue when right clicking.

You are right. Game is buggy. Would be interesting to see what you could do with the concept. Thanks for the submission
