Funny theme lol. Please do us all a favour and go into game setup on Itch and change the viewport dimensions to be at least 960 x 650 and disable the itch option for fullscreen. The unity full screen button isnt visible on the current page and as such I cant set the game to fullscreen, which I think would be cool to play in.
The game takes a bit of getting used to because you've got a detailed and colourful paralaxing background that makes it super hard to focus on the pillars that cause a game over. So its really challenging at the moment to get a decent score. Still I think the premise is funny and I appreciate the homage to an absolute classic. I think if you added just 3 sound sounds it would take it to another level 1) a flap sound when you hit spacebar (or maybe a Rick snippet from one of his many videos!) 2) A crash sound when you hit the wall 3) a free backround music track. Good effort and thanks for the fun!
