I also made a video with the full walkthrough of the game, including the collectibles. But if you're only missing a few, this written guide might be more helpful :P


Use ctrl + f to search your missing collectibles faster!
- Examples: "Armor Chest", "Lvl.3", "Fifth Defense Crystal", "Rai"...

It's a long guide, so if you spot any mistakes, please let me know!
Big thanks to WillowWisp for helping out in the discussions, and also to Onizucka, Vaharrak and Twinwolf for being so friendly and helpful!
