You should make a scuba mask "hat" and when it's equipped you can go swimming in the fishing area and if you buy a harpoon then you could hunt for fish but you'd be able to choose what fish to catch, you could make this into a side scrolling game.
For everyone who is struggling with the upgrades start off by getting mana regen X3 then get the thunder tower and keep upgrading that you can complete all levels with only 4 towers...
I would prefer it if [GOLD] [SILVER] and [BRONZE] medals were awarded on shots rather than time because I would be able to relax and take time on my shots instead of just rushing.
You should make an RPG style game like this but with randomly generated streets/missions. You could make a different game so it doesn't interfere with the Last Stand story. This would add to the whole survival and, this might just be me, but I never found a digital security lock which made the security skill seem a bit wasted. But if this was all randomly generated you could make a big warehouse (rare) which if you unlock the digital lock would hold lots of good equipment and food, but would also be full of trapped zombies. Also I didn't like how the ceiling seemed to break and 100s of zombies would just flood out which afterwards there wouldn't be any good loot and then when I go upstairs there is no hole in the floor. Anyway I really like this game 5/5 + Faved.
