Well, here's how I constructed my opinion on it. Graphics = half crappy (-1). Difficulty = A bit easier than prefect (+1.5). Upgrades = Good they are there, but they are crappy (-0.5). Grammar = Bad (-1). The effort = Not really bad (+1). Since the default rating is 3, applying all modifiers shown, you'll get...3. Yes I am giving you a 3 and if you polish it in the first place I will change my mind.
I would like a so-called 'keyboard mode' where the kitten is controlled with arrow keys or ESDF and Shift/A/Q/Z/W/Space for using powerups. And of course, the cat should have 9 lives. But it's still good. I give it a 4.
I like the music, and the way that the game is made 3d without requiring Unity. 5/5 because it's not that f*cking hard but still challenging and real-looking to keep you playing. I got B+ on my very first try. Good game. Huge thanks to Burstyx!
