hey,. yeah! I'm aware of all the bugs! I needed a bit more time to polish.. But hey, it's playable and it felt stupid no to submit it! . As for what made you jump, it was the color. When you turn Green X makes you jump! That's my plan for extending the ammount of things you could do with the key

I've created an updated version of the game! https://webox.itch.io/x-postjam if you want to have a better experience on what was my idea for the jam.. By now it only fixes movement and collision related issues. I'll be adding more levels and polishing more rough edges  this week!
