Yes, needs a remake
Gameplay is good but there are so much things which are destroying the game.
1. You don´t get money after beating a Level.
2. You don´t get money if your soldiers kill an enemy.
3. Every level looks like the levels before.
4. You have to start over if you die.
5. There are always the same enemys.
6. You don´t have your own gameplay, you have to skill the things with the lowest cost, so first you buy the more damage skill, then the faster soldiers skill etc.
So the game is okay but nothing for longer playing.
