Wow, what a great adventure we got here! Overall great in all aspects I could find. In particular, I never found myself getting bored with this: not only does the game keep introducing new fancy mechanics like the variations on the light beams, and not only does the game do a great job at making so many varied and unique rooms that showcase all sorts of creative combinations of said mechanics, but also the game varies between slow-paced puzzle-solving and fast-paced action platforming through traps which keeps things constantly feeling fresh and exciting! And what a lovely boss fight to finish it all off.
If I were to have any complaints, is that the game might be a bit too easy: never really had a serious head-scratcher of a puzzle and with 3 hearts it felt like the action platforming could be a brute-forced at times. Still, even that simple nature is a positive of the game: despite it being easy, it didn't stop it from feeling fun and addictive and a heck of an adventure!
