Cool game. I like the take on the theme with the ray gun thingamajigy. Gives off heavy portal vibes so definitely a unique take on the portal game style. The reflection mechanic is especially interesting as it had such a unique feel! :)
Some criticism i would give is that i had a bit of trouble with the ball and button level at the start, so i think something like an arrow would be nice. The cooldown was also a bit annoying as it felt restricting at times. But overall solid game, solid concept, and i wish you luck! :)
