In the update new content will be included as well as some quality changes listed below is what you can expect.
Quality changes:

-Sprite updates during development of  V1.1 we realized that the character sprites where too big  which meant they would clip  and we couldn't fit more then one character in a scene so we have gone through and resized them all which is the main reason for the update taking so long since we had to go in and manually replace all the sprites in the game files before we could continue.
-Sound design we realized that the game could become boring and bland without music or sound design so we are working on that.

New Features:

-Voice actors yes we got real voice actors not ai to voice some characters not all but a few will have someone voicing them.

-7 new characters in V1.0 we only had the one since it was just the beginning of the development and we didn't know how the game would be received so now that we see that people are actually interested in it character design is in full swing.

-As mentioned before music will be added for the moment it will most likely be just one track but as time goes on the selection might expand.

-A few new secret endings how many are there and how to get them find out yourself they are secret.

When can you expect V1.1 to come out?

We don't really have a deadline or date of release yet since we don't actually know how long it will take since we are new at this as well as the fact that we have a life outside game development since for the moment this is just a hobby 

Will the game no longer be free when its completed?

No since this is our first project it would feel bad to charge people to play a game that we might think as completed and good that might actually just be mild and boring other future games might be monetized but not for this one since it's our first ever game.
