About this game

HEAR YE, HEAR YE šŸ°

Tower defense fans, gather around, for your strategic thinking skills and castle merging abilities are needed. The King needs help reclaiming his lands from monsters, and you’re the only one with the brains to do it. This delightfully difficult strategy puzzle will really get you working as you merge tower pieces to create troops at just the right time to defend your fortress. Only the smartest will survive – think you can be one of them?

FIRE IN THE HOLE šŸ”„

Each puzzle level you’ll need to mine and then merge resources to create troops and equipment. The catch is that you can only do so many tasks at once – will you chop wood and draw water, or draw water and raise battle chickens? Time is of essence here as well, as the enemy is rapidly approaching. Protect your castle by skillfully choosing which resources to merge and when, and watch your kingdom and arsenal grow!

The funest features:

⌚ Tick, tock, tick, tock – You don’t have all day here! The countdown is on between each wave of enemies, so you have limited time to decide which resources you want and how to best merge them to protect your castle. Your brain will really need to kick into high gear to puzzle out which combos produce the most and the fastest. Balance how long each resource takes to mine with how much you need it, as well as where it is on the playing field in relation to your other resources.

āš”ļø Offense or defense? – Thanks to the combo of limited time and resources, you’ll need to get crafty and really strategize if you want to make it to the next wave. Unlike a lot of tower defense games you’ll need to be on your a-game when it comes to strategy if you want to keep progressing. And progress you will, as your skills improve, and soon you’ll be wiping out monsters like there’s no tomorrow as you explore all this roguelite puzzle has to offer! But first, are you picking the chicken warrior or the knight?

šŸ›”ļø Unique features – Not only do you need to choose which resources to have active when, but you’ll also need to make that choice before the battle starts as once the enemy has appeared, you can’t add resources to your playing field. This keeps the game fast-paced and exciting even for veteran tower defense players as it really pushes you to think outside the box. Don’t worry if your castle falls once (or twice), just restart the level and rethink your strategy!

šŸžļø Get a load of the graphics – Sure the game will really give your brain a good workout, but the graphics are easy on the eyes. Enjoy the cute characters and unique system for mining and merging – but watch out for that yeti over there!

THE FINEST FORTRESS IN ALL THE LAND šŸÆ

This game makes you feel rushed. You know that feeling when you are in a hurry, getting ready to go, but you feel like you forgot something? This game gives you that. I it wasn't for that feeling the entire time playing, with no breaks to get your head straight, it'd be a great game. Oh, it also seems to lack a main menu, or atleast I can't find it.
