RNG simulator 2020 (haha funny joke...sorry)
I like the blocky pixel art style, it actually stands out more compared to other conventional pixel art. (Easy, yet visually appealing, good work!)
But as others below me have said, there isn't a whole lot of gameplay.
The controls is very responsive and solid. (Although you can spiderman (get stuck) against a wall, lol)
All in all, a good start to your first game. I hope you can achieve your dream as a game dev. :)
