amazingly fun!
This game was pretty good! But heres some things to make it perfect...
1. difficulties
this is pretty self-explanitory, just make different difficulties :)
2. achievements
I really liked the achievements you added, but try to add stuff that you normally wouldnt do along with the regular stuff. (example: kill the final boss using only your pistol)
3. tiers.
I loved the tier idea for the weapons. But maybe to make all the 'make more weapons' people happy, and to add more diversity, you should start out with really crappy weapons. take the shotgun for instance, you start out with a really beat up one, but then next tier it changes (i mean by the picture on the side, how it looks on your guy, and all of the stats) to an ok shotgun, then after that it becomes a really good shotgun, and after it becomes some godly shotgun.things like that really spice up a game.
4. length:
this game was short. like, twenty minutes short. dont waste your great engine on such a short game!
5. enemies:
the enemies in this game were almost all the same. you should add new abilities for each, maybe some could be faster than others. you should also give the bosses better and stronger abilities.
6. levels:
having the same level makes the game a bit dull. after every boss, you should make it so the backround changes with new terrain, like a snow place or in a mall, and make the level bigger as you progress.
so yeah, thanks for reading this. 4/5 8/10
make it a 5 and a 10 when destroy all zombies 4 comes out!
