Iron Sea Frontier Defenders TD

Randomly refuses tower purchase upgrades you can afford between levels. Crashes occasionally for no apparent reason. Still fun as hell

After 5 loses you must wait until you can play...just an annoyance that attempts to get some cash out of you. Don't waste your time.

This game is identical to three other 8floor games with identical towers and mechanics: royal defense, sea defenders TD, dayD (dinosaurs), and now navy vessels. All versions are okay in the first world, but requires IAP for all later stages. Give this tired game a rest! Make some new content!

Plays well, although a bit buggy - specifically map 9 of the second to last world, which crashes 100% of the time about 90% through. Other than those annoyances, good fun and good graphics. A decent amount of upgrades and enemies - could use more diversity on the maps. But you can't beat the price, and don't need to spend money to have fun.
