So as it turns out, my new laptop is worse than I expected and it crashes every time I try to use Blender (my modelling software) on it. It can render low quality images with simpler objects (like the previous teaser), but I'm afraid that won't be enough to keep modelling and rendering objects and scenes for the game. I still have some programming to do with what I have currently, and I will do it, but I won't be able to model new stuff into the game until I save up for a better pc (at least 1-2 months). I might start making a new, 2D game while this is happening, but nothing is for sure. Thanks for your support!
