The new version of Jack's Journey is out! Any feedback is much appreciated!
Play it here: ahsen-games.itch.io/jacks-journey
Overall, I think the project is much better now, so I'll start to create the game content from now on.
LukeW and 
Windwalker, If you could play it again would be awesome for me. Your experience in the older version and in this one would give me a valuable feedback about the evolution of the game in general
Your game is very impressive! Great graphics, sound, animations, and polish. I don't have a controller to play with but a keyboard. I did find the Shift key a bit challenging to walk climb and slide, but maybe with a bit more practice. I guess I was expecting him to stick automatically if I push against the wall versus having to press a button to climb or attach to wall. Still, it's very inspiring to see this game. Good luck to you!
