I really liked it! The visuals are great, the island feels lived in despite not (directly) interacting with any characters. I love the small touches like the knock effect and the skipping stones, and also appreciate the alternate objectives that are clearly signposted for replay value / other endings. The stealth section doesn't overstay its welcome, and there's even a 0451 safe for good measure! Also the way to reach the apartment and the context about the tenant's situation was a cool touch.
It's got a bit of everything which, for me at least, amounts to a lot. Great job!
