This game is tons of fun! Thank you!
I have a few suggestions if you're open to them and plan on updating it at some point:
1. buying multiple levels of "Orb Level" would be awesome, rapidly clicking to bring new orbs up to even level 50-60 would be much easier with a 5/10/100/MAX option
2. The music either never plays or cuts out? I haven't heard the music yet at all (using the web version).
3. Speaking of the web version, it doesn't run if it's in the background, not sure if that's something that's happening because of the engine or a choice you made? I'd rather it run in the background if possible so it doesn't have to be in the foreground while it idles a bit.
4. The orbs very rarely get stuck on the flat top of the exit area dividers, if they were pointed instead that would solve this problem, I know you can click them twice to get them to respawn, just a minor thing I've noticed
Overall it's tons of fun and has taken up a lot of my time haha it's very addicting. Thank you for making it and sharing it!
