Bug/glitch: Double or "ghost" game session within same window
I did a few searches of bugs and glitches on the forums here but didn't see this mentioned before so I'm making a new post for it. Apologies if I missed a previous topic on it.
I'll describe the glitch first and then a bit about how I encountered it.
Essentially what happened is a second or ghost session of the game opened within the same window. I was at the main menu screen but there were two overlaid sets of menu options, each of which responded to input. I could scroll through both, and when I hit enter, both of them were simultaneously selected. They happened to be on different options, so, for example, the options I had selected were Multiplayer and Options - when I hit enter, I was taken to an overlaid Multiplayer chracter select screen and game options screen. I could still control both "sessions", so pressing the arrow keys both selected different characters and different game options.
When I hit escape I was taken back to the main menu, still with two overlaid "sessions". However, I hit escape again, and then one of the "sessions" closed. At this point the game seemed to have returned to normal and I could not get a double session back.
How I found this was I had played the first level a couple times and unlocked the second level. I played that for a minute before going to do the Spikes challenge. I tried that a few times and died, and then wanted to quit the game. When the "Try again" prompt came up, I hit "No" but accidentally hit enter when I got back to the menu so the challenge started again. I hit escape again and hit no, and this time rapidly tapped escape to get to the main menu. When the menu loaded, I had the two sets of overlaid screens.
I just tried to reproduce this by starting the game and going directly to the challenge, dying, hitting "no", and tapping escape, but wasn't able to get the same effect. I did get screenshots of what the glitch looks like if the developer is interested.
Has anyone seen anything like this?
