Thanks dude i'm happy to hear some feedbacks on such a small game like mine. I had some problems implementing sounds but it can probably be fixed easily. The boss fight is a cool idea I might add one or more in the future. Yeah the game is infinite and yeah the walls are supposed to bait enemies, I made them to protect the weaker troups like the Elf. The cooldown could be a great upgrade too. I can't promise I'll add all this features but thanks again for commenting pal I truly appreciate!
i'm glad to help! just curious about what problems did you have with audio?
when you do a more refined version (fixing the full screen bug where you can place mages outside the screen for example) i recommend you upload it also to newgrounds! you receive a lot of feedback there haha
About the walls maybe it needs something in the middle besides the flag or idk haha like meat?
and again glad to help good luck!
