Where are these guys? I've 100%'d all the worlds, slowly over time since the game was released on steam, so I don't actually remember where they were. They're my final two monsters to scan.

The error is - "Error preparing files to upload". The world includes couple of images created by mine.

This concerns the world Double Trouble, by BP, which is purchased in Oddness Depot. The red / right-hand version of the keychain level is not unlocking. I collected all the keychains and beat the blue / left-hand version of the keychain level, but this didn't remove the walls from the other version of the level. What did I miss? I have beaten and got full candles on every other level in that world, including the two secret levels....

Housing development I need the lunacy key to complete this level but I am a keychain missing and cant find another secret level.Any ideas?

Images have low quality. I use BMP format of course. Can you help me and explain how to save image, which format to avoid low quality?
