The music fits perfectly with the game. Shooting arrow is very satisfying, however, I swear I never found a good use for the triple arrow. The main reason for that is because in the heat of the combat, I find no time to look down to the corner to see if I can use the triple arrow so I abandoned that feature altogether. Got to wave 6 at my 4th or 5th attempt, it is really a hard game. If it wasnt for the limitation of the AI as pointed out by goblin I wouldn't have made it that far. Something I think you need to tweak is to leave the upgrades on the screen a bit longer, or even until the wave ends because it is very hard to get the item right away in later stages (only doable in first several stages). All those things I pointed out could be fixed very easily, I think you have a great foundation for a fun game. Good job!

Great arrow action and sweet arena map/music, only thing is movement gets stuck in a direction (permanently or shortly, at random) when moving while firing.

Movement seemed a bit strange at times and I got trapped in the corner for a little bit when I had the speed boost. Other than that the game felt great! Nice job!

I think the style was cool and did good on sound.   Mechanics were good, but noticed the enemy rapidly bumping the towers if it was directly in the line of site of player.  I failed to see where the theme came into play.  Unless the instant restart of the game was supposed to be it.  

I had fun and it is nice that you didn't have to restart, but eventually I just wanted to leave, haha.

Very fun little game. But it doesn't fit the theme
