Hello there Panji12, I am currently developing Mortui full version. Mr. Chainsaw series are on hold at the moment. After the Mortui there is secret bonus project. Generally, I like to develop FPS style games because there were few fps games back in PlayStation 1 era. The game already has lowest settings for the devices, further that will be unplayable. There is a lot of people playing the games on mobile from Brazil with very low-end devices. But this the much I can help the players with very low-end phones. Sorry about your issues but with current pipeline I am using i squeezed the GPU and CPU optimization to maximum as possible. If the Mr. Chainsaw download numbers increase in time I can make the episode 2 because story has already been scripted by me. Thank you for your interest about my game.
