At a glance this game looks almost like a student project, hell it wouldn't shock me if you told me it was. Most tower defense games the path is set, and for me being able to create and figure out the best path is %90 of the appeal of games in the genre, the rest is just grinding to get better towers until you can advance to the next level. There are so few TD games that let you path, so when i do get my hands on one I appreciate it even if it is a student project.

Its just frustrating not to have a resume button after a call PR multitasking. Better more in depth saving options would be awesome and also maybe allowing more waves through or multiple speeds to select to make it faster or slower. That'd make this the perfect game

I like that this game lets me create my own maze with only some obstacles to challenge me; in that, it's very like some of the games that got me hooked on this genre instead of those that restrict me to certain emplacements. Some of the towers don't seem to do much, but as I upgrade their abilities, they suddenly become indispensable. Sure, it's a 'pay-me' game, but so far, I haven't found it necessary to do so to advance, although I may, just to thank the creators. The ads are there, but they're not obtrusive. Overall, worth your time, I think, if you like Tower Defense.

It's worth playing, it has that old school tower defense vibe but it has some cool spins on the gameplay. I like the style because it's what I expect from a td, some of the newer bigger productions just water down td games with way to much stuff this on the other hand this is simple and fun.

It would be good if released 4 years ago. Now? I think that if you cant move on the genre or find something new and different then you need to find another way to make a living. Please dont just knock out a pointless tired clone. Game gets 1 star. Not because its dreadful, its worse than that, it's pointless.

I have made it to day four on almost all the levels. The only improvement that I think could be made is a more balanced turret ratio. It seems like reaping towers are the strongest and most versatile with all the other towers just being "ok".

I thoroughly enjoyed playing, it had me eager to continue after every practice wall, alas I had to uninstall, my smart phone screen cracked causing unresponsive touches right where I didn't needed that to happen. Until I acquire a new smart phone, i will more than likely reinstall & rate it to it's highest point. Cheers FridgeCat, I thoroughly got ingrained!!!

Too few towers and scenarios so it gets repetitive too soon, however it's a solid classic tower defense game.

Your inventory and progress isn't linked to your Play store account so you lose all of that when you move to another device. Really makes you regret using Play Store cash for in game items.

Good game. As with all these games its built then no new levels or armament or anything so after solving its done.

One of the best games Ive ever had....never stopped playing once I touched it. If only tech points were easier to earn 😂😂

Will have you playing for hours without realizing where the time went. (4/5 because if you get a call/go to another window you need to restart)

wish there was a way to undo or move upgrades/ points when I'm in the store an i accidentally hit upgrade on the wrong tower. other then that i very much enjoy spending what little free time i get playing this lol.

I have been a big fan of towerraiders for a few years. Since TR 1,2 & 3 are no longer supported, I have tried numerous other tower defence games, but in mere minutes uninsralled them as nothing came close to TR, until Four Days. I have enjoyed it emmensely and love the challenge. I have beat every level and finished every objective except one "Hall of Famer" Now ... when will the next levels be released? Is there a paid version being planned? Thanks for a great game.

It is completely free and ads aren't annoying as you would expect. There is a cap to upgrades but not enemy power in infinite mode. Only semblance of a story, but whatever. Focusing disabling vs air is almost impossible. No aoe for air either. Super hard to make a decent maze on any maps.

Easy to pick up and a lot of fun. Could use some more variety with the towers. Maybe a way to evolve a max tower into something else. Very few glitches but needs more to be 5 stars

This is by far the only game you need in this genre without the fancy loud lasers and pay to play power ups. Simple, easy, fun and addicting.

Awesome game. No BS story line really, ourstanding graphics, great controls and reasonably complex turret interaction.

Jef. L. Mar 23, 2015     

This is a decent game, but for some reason, I cannot play it with the stylus on the Note 3. It is the only game I have that ignores it completely.

Deleted after first level. Not easy to advance. This how money is made with the app. Oh well, spend my waisted time on something else.

You have no time to think and build. Not only cannot you build while paused, you do not even have time between waves.

Have been looking for another game like it (for android) for years...difficult enough to make it fun and challenging, yet still beatable. This has been my TD standard for years and no TD games have quite lived up to this one. Nice thing about this game is you can beat the whole thing without paying a cent if you are patient and use the permanent tower upgrades in the main menu....earning permanent upgrades makes replaying levels fun. When all unlocked and beat, reinstall&start over after a few weeks/months

Been playing this for about a week now. It is very entertaining, very challenging and pretty darn addictive. I will definitely search for other games by the creator and would recommend this game to everybody.
