I liked this artstyle and gameplay! I will say that the 1 color background made it hard to tell where I was moving to, as everything else is moving to. I liked the music as well :)
I love the color palette and artstyle! Very nice level layouts as well. I did have a hard time telling the 2 guys apart and would end up just mashing the walks to try and tell. I also feel like a little controls panel was shown in the empty space on the sides. I hope to see more levels :)
Very fun! It's crazy you did this on your own too. I loved the moving and the train concept. I did get stuck when I only had the white car that I think only pushes enemies so I couldn't kill them after that.
I can't imagine doing all of this in one day! I'm not a very good gamer so I did not make it far, but I agree with other comments that having a damage meter for enemies would be good. I also wish the time slowdown was enough to get out of the way of shots but maybe I just need to get gud.
Very fun! I loved the art, but I felt like I wanted to collect something as well. I was so close to 500 but I just missed it T^T The art is beautiful and it felt very intuitive.
