Pretty nice game
I think this was a pretty nice game. Of course I´ve seen games that were better, but this one was pretty good still. It had some nice music, which is pretty important. I also liked the day and night time thing and that it actually turned dark. It isn´t really usefull or anything, but it just looked nice. As for the rest, I also liked the upgrades and the enemy guide. There weren´t that much different types of enemies though.
There were also a few things that could use some improvement in my opinion. First of all, I think the battleground could use a few more details. It´s only some grass right now and a brown path through it. I think it would be nice if you added a couple of trees, bushes and some water. You could make a few more enemies as well then that hide under water and in the trees. Second, I think it could use some sounds. The music was pretty good like I said, but it didn´t had any sounds at all. Third, you need to work a bit on the castle. It was just a square with a few smaller squares in it, that didn´t look good in my opinion. You don´t have to add a lot of details in it, but this just looked a bit simple. Also it could use some better special effects. When a fireball hit the enemy, it just kinda dissapeared, it didn´t to anything spectacular. It would´ve been nice if there would be a small explosion there. Fourth, I think the giants appeared a bit too quickly. At level 5, I had a huge castle, 2 times faster spells, 1 time more powerfull fireballs and 1 tower with iron arrows and I still barely had a chance when a giant appeared.
Overall 7 out of 10, 3 out of 5. Well as you can see, I think the most important thing that you need to improve is the graphics (battlefield, special effects, castle etc.). That´s too bad since the graphics are one of the most important things to me in a submission. Anyway, even though it could use some more work, I still think it was an alright game. Most of those ´defend your castle / base´-games are pretty cool and challenging. Keep up the good work.
