"You're a cat with a Glock, chasing your high score on the run" is the whole pitch and it's already funny.
This is pure jam energy and I mean that as a compliment. A white pixel cat holding a pistol with fire coming out of the barrel, pasted over a stock photo of a snowy mountain. It's rough and it's great. But the hand drawn Paint cutscenes are the best part: a scribbled arcade with an ARCADE sign, then the cat playing a machine labelled "Highscore Chaser" with "Highscore x69420" on the screen. I laughed properly. That communicates this jam's theme better than a lot of much more serious entries. And having a LEVEL SELECT going from 0 to 5+ suggests there's real content here rather than one room.
Four things to fix, all quick. The main menu literally says "UNTITLED GAME", the Unity template placeholder is still there. Swapping that for the game's name is 30 seconds of work and it changes the entire first impression. No button responded to a single click, only double clicks (START, the levels, the cutscene arrows). Level 0 wouldn't open at all, only level 1 worked. And in the cutscenes the text on the right is clipped ("I HA... SHA... MY...") because the game window is wider than the screen, so I lost half the joke.
Fix the title and the clicks and this becomes one of those daft games people actually talk about in the jam thread. The cutscenes deserve to be seen.
