Never played anything like it (in a good way). Really really unique and cool concept, super creative, well executed.
I will show that to my little son and my girlfriend who usally don`t play any video games.
I think they will be blown away, by that type of gameplay.
The 3d graphics are nice, game looks good. I like all the "physic" interactions. I like the player figure and "enemys".
I would have loved to have a back button, I kind of not understood what to do in the second level. (that i had to start from the "pen area" (probably my fault). I was confused and thought maybe i have to use different colors or something, because the other crayons were also highlighted.
Than I reloaded the page to start back on level 1 and I understood what to do ;)
Music and sound effects are mostly fine but the biggest bummer for me were some too agressively loud sound effects, especially the bear or the heart.
I also had some problems with holding the mouse for so long to draw the route, but I could not image any better way to draw, besides maybe touch input.
I could see this also be very cool to play on a tablet. Very good submission! you can be proud! The name fits the game very well.
