Hey, thanks so much for playing, and leaving your thoughts! I'm glad you enjoyed playing so much. I agree that with more time the upgrade screen and UI get do with a little more polish, someone has suggested that being able to zoom in / out would be helpful, perhaps have a button to toggle on/off the other UI elements to minimize the clutter onscreen could help too.
You're right that the main menu music is a short loop. The reason was I was trying to go all in on a Main menu that transforms into the game, and didn't want a jarring change of music when the player pressed the Start button. That combined with the fact that the opening transition into the TV is timed to fit with the way the music swells meant that all i backed myself into a corner with what i could do with the music. Trying to be as seamless as possible and then be correctly choreographed to the cutscene...the trade of was looping the beginning of the music until the player pressed Start. Thanks so much for pointing it out, because as the developer I never spent long enough on the main menu to find it repetitive, so something I'll think about in future games for sure.
