Thanks again 40wattstudio.
How did I miss Falcon & Prometheus!
I'll add effects to the projectiles of bosses so background issue should be fixed then.
Maybe keeping elements collected after death could be cooler.
"Sell All" idea is good and easier. I'll try that way.
-I have an issue with sound on higher levels. I'll also try to fix audio mix. When higher ships shoot and hit the target, there becomes a huge noise issue. (As each bolt has it own audio) I am working on it, couldn't find an idea yet but I will :)
New update is coming soon then! And, thanks a lot again.
