I think the name is pretty self-explanatory. It's just RTX Morshu with some other places, like town or forest. Some endings are actually hard to achieve, the hardest one is the one when you bomb grubhub or buy everything from Morshu. I spedran the second one in 55.54 seconds, and with the built in timer, speedrunning is really easy.

RTX Morshu 2d. You want it? It's yours my friend, as long as you can download 90 megabytes of data.

Open shop but with gun speedrun in 16.81 seconds
