Wow very entertaining !
+ Chain explosions !
+ Interesting weapons, very interesting and well designed "specials"
+ Cool musics, I appreciated the change in mid-game. Maybe even more musics...
+ Excellent sound effects of weapons and zombies
- Dull Defenses upgrades
- Graphics are a bit amateurish
- A bit easy. Mainly for 3 reasons : too much ammo (i never bought any and had tons of it), starting weapons are too strong : you can pass half the levels without upgrades. Also, upgrades of weapons seem useless, since benefits are so small. And finally, zombies arent damaging the barricades... we need more punishment :)
- No end boss ? :D
Good work, ty for the game.
