Just finished the game and it was really good.
The pixel art looked absolutely great, and you did a really nice job on placing a lot of sound effects and such to each action. The animations for some of the art was pretty well done too, like what I assume to be tweening for the dialogue/interaction boxes as they pop up.
The mechanic with Kayden was pretty interesting too, though it took me a little while to figure out that you could left click to move them.
I do have a few small nitpicks though. The pixels on the character sprites are really big compared to all the tiles, which does look a bit odd. Some of the objects are missing collision boxes, but it really doesn't affect the game too much.
The left click mechanic was hard to control at times aswell, not sure if it's just me (playing on a standard 1920x1080 monitor) but Kayden just would go where I clicked most of the time, which was somewhat annoying.
I also found you could softlock the game at times, my first softlock was when I encountered the 2 blue buttons, I was testing some stuff and Kayden went through the first door as I was holding the button, and there was no way to get them back out so I had to restart the game, from there on I played the game really safe but it did look like there were a few more spots you could softlock the game as well. I'd suggest adding a restart or reset button to help deal with unexpected softlocks like these.
Another pretty small suggestion would be to possibly highlight objects that can be interacted with, as I didn't notice some of them the first time I played, and it would possibly help show the mechanic with Kayden having to be on the screen a bit better.
Overall, the game was really fun to play and super charming, so good job!
