Thanks for playing. It's tough to add variety with just a game two code reveal mechanisms and three monsters, we hear you, but it's all we had time for in 7 days. The code reveals do get more obscure as the levels progress and the monsters get harder (but the weapons get bigger!), that's all we could do. The "Rest Room" was another gratuitous waste of development time but I had that itch that I had to scratch! Glad you enjoyed it.
