Yay I found Felix! This game got me hooked, the visuals for some reason reminded me of some PC games I used to play back in the day. The music also has a nostalgic air to it.
But the thing I found pretty interesting, and that I don't see quite often, is a combination of WASD movement and point-and-click mechanics. I think it worked pretty well in this game because it makes you feel like you're the cat, and not some detective observer with a pointy click and an almighty view from above. Good job!
