• Dev Log Preview: March of the Druids - 11 September 2026

  Druids are an enemy that become more of a nuisance the longer they survive. Starting from level 1, they are able to periodically transform into their bear form making them much more deadlier. While in bear-form, druids have additional temporary health, increased movement speed and increased attack damage! The more transformations a druid is able to perform, the most damage he is able to soak from the dungeon's defenses...Brambehorns is ultimate druid, come to pacify your dungeon. In the final nights leading up to his arrival, he applies the roots of Bramble's Curse to buildings in the dungeon.The roots prevent the affected buildings from activating and require assigning minions with the mining skill to clear them. If not cleared in time, you might find yourself defending without your most powerful traps in the final encounter! Like his druid brethren, Bramblehorns can also transform int…

• Dev log: Munchkin Hero Preview - 7 August 2026

  Here is sneak peak at one of the enemy hero types we are working on for the fulll release...Munchkins enters the dungeon as high-health slow moving units, but they pack some tiny surprises. On defeat, a Munchkin spawns a group of smaller, faster Munchkins which can quickly get overwhelming if not dealt with!Higher-level Munchkins spawn with the Hat of Mischief item. Be wary as when you defeat these guys they will permanently reduce the damage of nearby buildings!Bringing up the vanguard for the Munchkins are the Bosses Hansel and Gretel. One is used to fighting in close-quarters while the other excels at attacking from range! These twins bring an extra level of trickery!

• Changes based on your feedback - 30 January 2026

  We received a lot of great feedback from our last round of playtesting. Thank you again to everyone that participated. Here are some of the gameplay changes we have in response to the new insights.New rock shapesOne thing we consistently heard is mining often feels underpowered and players want to engage with the mining mechanic more. However often it was expensive in terms of the number of minions required to mine out a large section of dungeon. In the latest build, rocks can spawn in a variety of tetris-like shapes include 1x2, 1x3, and L-shaped blocks. This randomization allows for the creation of larger spaces to build traps or death corridors requiring fewer mining minions, as well as provide interesting geometric decisions about how to carve out the shape of the dungeon. Meta-ProgressionA feature that was heavily requested was some form of meta-progression. While we were initially…
