In Elona+ [official site], your backpack can crush you to death. In most games, the worst that is likely to happen if you’re overburdened is a reduction in your speed but in this excessively strange Japanese roguelike, the weight will drain your health or cause you to trip, fall and break your face open as you try to navigate some stairs. It’s a game in which you can make money by busking with a grand piano but if you’re not particularly talented, don’t be surprised if your audience stones you to death.
Yes, you should be playing Elona+ and what better time than now? Version 1.49 and the relevant English translation have just been released.
