Pretty good game, a few improvements needed.
It was a pretty good game, I liked it. I didn't last all 25 waves, though. I made it to about Wave 22. I liked it, but some improvements are needed.
One thing is the hit detection. An enemy could hit me, even after I was well away from them. It seemed like once they swung their weapon, I was hit, regardless of where I was on the screen.
A second thing would have to be the prices of the potions. Why do they increase every wave? Some rounds, I was spending all of my money on potions alone, and it still wasn't enough to fully heal me.
Finally, nerf either the difficulty a bit, or the enemy's health. Even with a Compound bow almost fully enchanted, with all but Speed maxed out, I still couldn't kill most of the enemies. It was taking entire round for me to do anything, from about 17 onward.
Overall, it was a good game. Just improve some of the mechanics in the game, and it'd be perfect. 5/5 and 9/10 from me.
