Love the visuals, i used Kenney assets too :)

Nice theme interpretation

It definitely lacks some explaining the rules and controls. I just aimed starting laser at end station,  but the level didn't end so I don't know if I guessed the goal and it's not implemented yet, or the goal of the game is different.

UI seems to work fine in fullscreen, but in embeded screen, level number and pause button are cropped.

The idea itself has potential but right now it's hard to judge because the gameplay needs more complex levels.
