I could not get past the second jump, and I tried for roughly five minutes. So I’m just going to give some advice instead of commenting much on the actual game.
My best advice is to play the good platformers out there as well as the good rage games. They always make it so you feel like it’s your fault you messed up, not the game’s fault.
That means generally:
- Be generous with hit-boxes (favor the player). This makes the player feel like they messed up, not blaming the game.
- Do no hide mechanics required for progress.
- Ease the player in. Make difficulty progress throughout.
As for other feedback: The cat was cute and the ground sprite was decent. The rest could use some work, and your game page should use a different and larger font. It’s difficult to read. Getting stuck on the walls was not something I enjoyed, not was the slippery player controller in a precision jumping game. The main menu looked good and I enjoyed the aspect ratio not being 16:9. It fits the pixel art style.
I like thinking of games as the same as good user interface design, you want to reduce the mental friction as much as possible anywhere it’s not an intended part of the design (in 99% of cases you want less friction).
