Very solid game! Polish is perfect, colors are nice, sound is on point!
The mechanics are surprisingly fun, I enjoyed figuring out the different icons' meanings :D
Like some others said, it sometimes felt like I solved a level randomly by just putting the actions in random slots. But that might not be a bad thing, especially early on in the levels!
Little bug I found (you're probably aware of this): you can drag several actions at once with your mouse
Small nitpick (especially for the web version): wish there was a button to exit the settings, I had to press escape to go back, which un-fullscreened in the process
