This is an awesome game concept. I easily spend hours playing games just like this on my phone -- except, I think yours is better! If you exported this to WebGL, I'm pretty certain more people would play.
- The music is awesome. Given you created this 15 years ago, I'm super curious what your compositions would sound like today.
- The music actually stops playing after both songs have been played to their end, so you might need to enable a loop somewhere.
- I've also noticed that some upgrades (e.g., auto-shoot) appear to carry over across lives even though I got my money back from upgrades? I saw in the instructions that this happens, but maybe only one of the two should happen? (either get the money back or keep your upgrades)
Either way, I really hope you continue working on this and publish to the app store or Steam. Adding to my favorites!
