Some scenes can take me a lot of time to make ;(, so in that way I'm trying to put all my efforts in making a scene look good instead of having too many events on one update, sorry about that u_u.
About the second part, I always leave a "Save" folder inside the .rar (right beside the game's folder), so that way you can just copy that "Save" folder inside the game's folder and start playing just at the beginning of the content :).
Or in case you want to use your own saves from previous updates, you can just copy your save folder from the last update and paste it in the new game version.
Thanks for the support :D
