Initially I have started spamming shots at the target before I figured out only the bounced ones do the kill and it escalated quickly haha but on the second go I was more deliberate with my shots an cleared all levels.
I think the UI is awesome, especially the main menu looks very immersive. The core game mechanic is also well designed, it naturally increases the difficulty as you go.
I'm not sure where you would go from here if you wanted to turn it into a full game though, let me know if you have any thoughts!
When you have the time let me know what do you think about my game, feedback is very appreciated:)
