Incredible system, I've had a deep love of video games and ttrpgs my entire life and Lumen is just an unbelieve marriage of the two game design philosophies. Fast Combat, High Damage, Lots of Loot. I highly recommend reading this through if you're looking for or creating a fun TTRPG to get people to 'buy in' to the hobby!
Great little Resident Evil card-laying dungeon crawler. Does a good job of balancing the dungeon navigation challenge with journaling to build our character and our connections with our team members.
It also works surprisingly well as a multiplayer experience, with all players collectively controlling the single IRIS member.
My only suggestion/wishlist item for a future game would be to add an explicit multiplayer mode, with each player controlling their own character.
