It don’t even teach you any strategies. and there’s one level that’s completely unwinable! ### 4/5 — Нормис *2024-07-30, version 2.4* Сложная, что бы были донаты. Играть можно. Каждое движение на грани проигрыша ### 3/5 — Left unfinished *2023-04-05* Fun game. I wish it were finished. It took quite a while and a lot of different strategies to beat every level on hard. I wanted those locked turrets so bad! But last update was 5 years ago. While I believe it’s dead, I would be happy to be wrong. ### 1/5 — Bug report *2023-02-14, version 2.4* Hyperion system, map 6:3 “puzzle map” hard is impossible, on the 5th run. will update review when fixed! ### 5/5 — SO MUCH FUN !!!! *2022-01-16, version 2.4* This game is so addicting!!!!!!! ### 1/5 — Horrible *2021-12-25* horrible, pay to win and pretends there are more weapons and levels but after you complete everything it just says “coming soon” ### 5/5 — Awesome *2021-12-23, version 2.4* Good game ### 3/5 — Super! *2021-06-21, version 2.4* Super Game, just very hard and ads after ads :D ### 5/5 — Update *2021-03-27, version 2.4* When will you add back encyclopedia and the next 3 campaigns? ### 1/5 — Can’t progress *2021-01-04, version 2.4* It doesn’t matter how many upgrades you buy you can’t advance beyond a certain point because you either don’t start with enough money or you don’t make enough killing the enemies to buy or upgrade towers fast enough to beat the level. This game hasn’t been updated in at least 3 years so I’m not sure why it’s still being advertised, it’s a waste of time. ## Frequently asked questions about Tower Defense ### What is Tower Defense: Alien Demons TD?
