I watched the video, it was very cool! Yeah you are totally right, the trees look a bit off because they all look the same. Tbh I didn’t notice that, but since you said that, I see that too.
And yeah the invisible walls are really a bit too much, but I wanted that every player has like the same game (like a linear game), so it was easier to program for the first time.
But the next game will be bigger and not as linear as this one.
It may take a while but I can ensure you - it will be at least double as good as this game.
Thanks and greetings
