Game has a lot of charm and there were no bugs in my playthrough. Overall it's fun but a little short and missing a few features (listed below), I finished it in under 20 minutes. I wouldn't say it's worth this price point in it's current state, but I'm always happy to support an indie dev who clearly has a passion for game making and if my purchase will go towards future projects then it's worth it for me. Look forward to seeing what you do in the future :)
Needed features-
-An explanation of the controls somewhere in-game or in the menu
-Background music, even just free Kevin MacLeod stuff would do
-Sound effects you used are good, but could do with a lot more.
-The colours puzzle was a little fiddly. I'd suggest changing it to buttons that change the colours instead of pushing, but if that's not possible then just a simple sound effect letting the player know when it's hit the right spot will help.
-Finding the cutters took a while, give the sprite an animated sparkle or something so it's easier to spot
