1. At the end of the game I literally mention that you can do that. You can skip like 5 sections.
2. For the 'they kill you once' thing, the game would be much too easy otherwise, as because the game is pretty short, I needed to lengthen the playtime. However, if you did see the ending, I also kinda knew it was brutal, and that's kinda the story lol.
3. I know this is coming up, but yes, when you attack, unless the attack is done, you can't jump. Killed me more times than i'd like to admit, but its fun to see.
Anyways, thanks SO much for your feedback, I'm happy you actually PLAYED the game, so thx!
