It's like a simplified board game based on the D&D campaign "Tomb of Annihilation" without the roleplaying. I normally enjoy the depth and complexity of RPGs but I must admit that this is done very well and being able to casually start and play a mission for a few minutes without having to get deeply invested is an enjoyable change of pace.

Overall, I highly recommend this game, but be aware that it's a single-player D&D board game and not traditional roleplaying.
