The first character, the Detective, is very fine. It's definitely playable without the need of grinding. The second one, the Professor, doesn't really make sense. In the jungle levels, under easy difficulty, I literally need to use artifacts such as invisibility or invincibility for at least half of the room. I mean, yeah, sure, it's definitely "playable" if you decide to grind for maybe 20-30 invincibility and the same amount of invisibilities. But hey, it's just a game. If I need that kind of grinding, I better grind for Leetcode. At least it pays. The other parts are fine. Art and sound are both good. If you like grinding, buy this one, otherwise skip it. Life is too short -- plus grinding on a randomly generated game even makes less sense.
