Thank you.
Yeah the game can be super difficult. For now i dont know if i will invest more time on this project. It was initialy only for Harvard Final Project and Unity CWC like you said. But if i do i have already some BackLog for the difficulty. And yeah i need to let player know where to find the demo (esc for pause menu => demo btn). And i have a prob with UI who scale not correctly on WebGl (look bigger than in PC or standalone build for no reason).
Thank you very much. And let me know your project ;)
