I really love to learn the other's experiences or how they turned into game developer, because you know, that's not easy to meet in real life another game dev by luck x)
And like you, I'm 18 and I've got a big project hopping for steam ! I'm felling a bit less alone in that quest
And yep like I've said, I've finished your game until the end menu. And that's exaclty what I've felt when I saw the end. "Wow that game is not finished". The mechanics were really cool, like the boucing of the cube, and also the game design was well designed. Colors, placement, that's a good job. But the end for me is the more important ! All of the work you have made, take the player until the end with this hope "Surprise me !", but when we arrive at the end, THIS IS the end x)
And that's a bit sad for me. I hope you don't give up your game, and continue to polish it, adding a REAL end and orther mechanics with your fucking skills ^^
So sorry for my really REALLY good english (as a french , google trad is my dad)
Then I'm gonna try some your games !
