I liked the title artwork, and the ability to adjust how much of the top and bottom screen you can see at a time was cool. That feature does speak to a potential issue with the current design though: the two worlds don't seem to interact at all. It seemed like the ideal strategy was to pick one screen to focus on, get it to the end, then switch to the other one. It would be cool to see some interaction between the two worlds in a future version. Some additional notes:
- The visual presentation of the tutorial was pretty good.
- At some point the tutorial had a character say something about my having died and left a corpse behind, when I actually hadn't died yet at that point.
- The tutorial did not seem to recognize when it was completed. Either that or I couldn't tell where the exit zone was, but both worlds had what looked like a door that I had both characters in front of
- The main menu is bugged. After returning to the menu by any means (in my case after manually quitting out of the tutorial), none of the buttons worked
- In both the tutorial and the main game, the music stopped playing after a minute or two, probably best to set to looping
- As far as I could tell the main game (or what you call hard mode in the menu I suppose) didn't have an ending? I couldn't get the top character to their first checkpoint, but I got the bottom character to a point where the world just abruptly ends with nowhere to go.
