Quick comment on the prototype: put in a QUIT GAME option that doesn't force the user to ALT+F4, and put a killfloor under the level, with a respawn at the nearest safe point.
Regarding the READ ME file, I'd suggest putting that info in the game description as well, don't create additional steps for a player to enjoy your game.
This said, the basic concept is still a little bit foggy, it kinda feels the main mechanic should be introduced immediately, a few seconds after the player grabs the arm. Do it the reverse bioshock way: introduce me the mechanic, make me have a little bit of fun with it, THEN hint at the world, at what it hides from me, at its story, its lore... its secret. A mechanic has to be as interesting as (if not more than) the game world, to hook the player in, especially in this shorter almost experimentative prototypes.
Can't wait to see where this goes, for real. Great job
Thanks for testing the build and for the feedback!
As it was an old build, many things were missing and we are now working on the feedback of the interactions (VFX and SFX).
We added a new build (0.5.1) made last week which gives an idea of the direction we intend to take with the title.
The project is a test in progress, but we hope we will be able to reach the goal or learn from our mistakes!
Thanks again!
P.s.: In the next one we will include a tutorial .-.
