Pretty Good with some things need fixing (will update if fixed)

The game is pretty well balanced. The game is pretty free to play. I like how you can pretty much create your own tower defense path with some restrictions. I do wish you could flip the rotation of the javelin trap. Having it only attack upwards can be a bit frustrating. If you can fix the rotation of all the medium to long traps, it’d make the game a lot more smooth. Also if you can make the “ALL” defense towers be able to target first unit. Make it interchangeable like Bloons Tower Defense. The Skeleton archer never targets the first unit or boss units. It just targets the closest/random unit to it.

Insanely Good Game

This game is perfect. Constant progress and no forced ads is such a relief. However if we could fix multiplayer bugs like the random invisible towers that would be great. Also it would be nice to have my already equipped items and take them into multiplayer. and it would be even better to be able to rotate towers to get even more powerful tunnels. Just some constructive criticism but overall 10/10

Refreshingly original. (Ai ahhh review, but I promise I’m not)

This game is truly a stand out amongst the copies usually littering the App Store. Finally, a game that IS a game, not an ad with a hint of game, an ACTUAK GAME. It truly makes me happy, to know that there are people who still think of their consumers. Give the game a try, you won’t regret it.
