A decent start and it has the potential to be an interesting type of TD with this style and the fact that you're using LoZ, but will need some work and much more development.
A more structured and developed tower system, upgrades for Link, and general info (tower stats, range, speed, etc.).
Use what you have, the arrows and bombs, otherwise no point in having them on the screen.
A manner in which to gain health back as it can be lost both, by touching and by passing enemies.
Perhaps a shop could be of some use or a pause feature.
Reviews for "Zelda: Hyrule Defender"
not all that,it's ok,but not AWESOME.
no upgrades=pointless. and I'm slow at these games. I need time to place towers. You give almost no time between waves to get back in place and set up towers. Once my towers couldn't keep up with the flow, it was game over
Good................................b ut where r the UPGRADES??
uhm yea... the game is not bad... feels nostalgic to play this
but the language really needs some improvement. I know not everyone speaks English fluently (tbh my English is anything but perfect) but if you know that you should ask someone or help.
