I liked the camera movement.

Awesome game, I got to the end - it was a ton of fun. I had the hardest time on the second or third bounce platform that is introduced right after the bounce platform sandwich, it took me a while to figure out I could increase the player momentum by adding a double jump at the peak of each bounce, I thought the physics were broken on my pc but after I figured it out it made total sense. I think the issue for me was no sense of speed change, making me feel like the velocity was maxed out when it actually wasn't. I really like how the player speed slows down when the player shrinks just as you start to get used to the movement, it keeps the simple platforming interesting. I really like the art style in the intro and conclusion too, does a great job at giving the gameplay a sense of purpose. Great work, tons of fun.

Great work! Awesome music and plays very well. Decent length and good variety of gameplay! It was a tough game but I am proud to say I saved the cat.

Here are a few suggestions...

• Use the littlejs.release.js version, this is slightly better perf and will remove the debug watermark from the top right.
• The shift dash mechanic would feel better if it recharged instantly when you land. At least I found it somewhat frustrating. You could do this by checking if this.groundObject is set.
• There is slight bleeding in your player in some of the animation frames. There are 2 ways to fix. The easiest is to use setTileDefaultBleed(.5) which will shave off half a pixel around the character. The more correct way is to use the padding setting, and modify your sprite so there is a 1 pixel padding around each frame. The platformer example is set up like that for reference.
• The intro is great but it would be nice if there was a way to click through for repeat plays.
• It would encourage players to finish if their game was saved. You can just store some json in local storage.
• There is good progression of mechanics but not of scenery. Even just simple things like colors and shapes can make a huge difference. For example one idea I had is maybe as you progress to the right the sun is slowly setting which changes the colors in the background a bit.
• You could integrate the cat more, remind the player that is the goal. Like maybe at each checkpoint the cat is sitting there but when you get close it runs away.
• I also thought the shrinking mechanic was under used but I just had a funny idea for the end. What if you shrink then the cat chases after you trying to eat you! So the cat is like the final boss, a chase were you need to keep moving.

A glitch in this game somehow caused all sound on my computer to crash 😅 a glitch in the trampoline blocks caused hundreds of sounds to play.

What a delightful platformer. I completed it in about 30 mins and I enjoyed it a lot. A few minor issues I found are the bouncy platforms that make a lot of noise when you stand on them and the bg music that doesn't loop after a while in the same section, but otherwise it's a really polished game with a lot of variety in terms of power-ups. Congrats!

It's challenging but it's fun, took me some time to reach the end but I like the process

I really liked the introduction.
