This was a fun short platformer game! I liked the theme you were going with inside the computer. The file transfer bar and windows helped add to this. I liked how in the last level you had to go outside of the window space to complete the level. I didn't realize it was somewhere I could go until one of the collectibles appeared there, so that was a cool surprise!
I had a little bit of an issue starting the game at first since I didn't have my controller plugged in and wasn't sure what the start button translated to, but once I plugged in my controller, it all worked well! The start button ended up being a different button though. And the window size (I'm not sure if this was intended) was set to the left half of the screen and I wasn't able to resize it.
Other than those few little bugs, this was a fun platformer with an interesting theme!
