The visuals in this are top notch, the sound effects are pretty good, and I like the music as well. I could see a game like this as having been an actual release on gameboy, so that's nice too. I also appreciate the way the music changes a bit based on what's going on, with minimal simple music playing unless stuff is happening, and when stuff is happening a more complex song plays, instead of just playing one song on loop the entire time. Nice touch!
The concept of catching the greebles is fun, as is the shaking a bunch of objects around to find them thing too. Really gets across the feeling of playing as a cat quite well, heh. Also, the usage of the theme here is quite good, the game definitely has the right atmosphere for it and manages to fit it into what the gameplay is quite well.
I dunno, the pouncing, it works well. The game feels right overall. That's a tricky thing to get right, and you got it right.
Also? You... you got that jumping mechanic working. That's impressive. A multi-layer system of some kind that allows you to jump up onto higher surfaces that as far as I can tell works basically without issue in a game with otherwise purely 2D gameplay. Yeah. Yeah that sort of thing is hard to get working at all, and it working with relatively minimal issues... not gonna lie, I'm kind of impressed by that.
...admittedly though, while I like the concept of the gameplay, and I'm impressed by the jump, and I do overall like the feel of the game...
...I think that the whole "flee onto another screen if you ever take damage" thing was the source of some frustration. Mainly because it's bugged and can softlock the game if one of the damage-dealing greebles manages to make it to the edge of a screen such that you take damage from a screen you're not currently on, or if you get hit a second time while fleeing on the same screen, which forced me to restart the game multiple times.
I uh, also ended up fleeing through a wall sometimes? And uh, one time I fled through a wall, into another wall, forcing me to restart once again. Yeah it's a really buggy mechanic as-is.
Programming is hard sometimes though, I get it. These things happen sometimes, and while it impacted my ability to enjoy the gameplay, it didn't outright ruin the gameplay. I mean, it's honestly mostly made up for by the in my opinion impressive programming on the jump mechanic. Almost.
I mean... I did almost give up when I learned there was a basement room and it was yet another softlock for me because it's another of the few screens in the game to start with a large greeble out instead of having it hidden in something, meaning you can't risk ever leaving the screen until everything is cleared out... but uhhh, I did ultimately finish the game and had a good time, so...
Overall, despite some issues, I still did ultimately have a good time here! Good game.
