Editors’ Notes

Hold back the hordes with cannons, ballistae, and your own hero in this action-packed tower defense game.

Great game, reasonable progression

Short version: great game, great progression speed, very fun, good design, not a cash grab. I love it and praise the developer.

Long version: I’m really impressed with this game, it’s fun and the progressing rate is very reasonable. There is the option to watch adds to speed things up a bit, but it doesn’t make it painfully slow if you don’t watch adds and none are forced on you, so it really feels optional and like you’re actually purchasing a benefit, not removing an annoyance. On top of that, it is a permanent add removal, but the “watch an add to get x” options stay and just become free. So I absolutely paid the reasonably priced remove adds forever button. It’s no different than if I had to pay that price to buy the game, except I got to trial for free and there’s extra benefits. I’m impressed, it’s an actual fun game, not a cash grab, and I hope this developer makes more, this is a rare find today and I’m super pleased.

Best tower defense

This is the best tower defense I have played in years. This would be an amazing game on pc or mobile. The amount of game depth while not becoming the over cluttered mess that balloon tower defense has come is incredible. On top of that a great art style and theme keep it interesting . Lastly and the most important, making ads only help, and not mandatory, make this a 5 star game 100%.
Not to developer: if you haven’t already please port this to steam. As long as it’s not to demanding, would definitely purchase it for pc. If you do release it to steam, I would just release it at 15-20 dollars, and remove the ads and just make it a in game gambling system. Your game play loop is more than good enough for the price tag. You could even remove the auto elite rolls, as pc players like grinds.
