In the middle, 2 visuals:
a basic sawmill
and then the same sawmill but in the style of Smay Patrick Meme, with a mouth and long nails, very cunty

It's time for you to learn about HER ๐Ÿ’…

We just like the sawmill too much. Don't ask any questions, I don't have the answers.
I just know she's an icon, she's a legend and she is the moment.

(the cunty version is not in the game sorry)

If you like strategy games, you probably like stats. And these icons will help you figuring out a plan so you can win!

These are the items you can loot in Hold the Mine. Some are ressources, some allow you to recruit or build, and some have a huge impact on the mine's tiles! ๐Ÿ’ฃ๐Ÿ’ฅ

This is how we made the animations for the game with @camillecee.bsky.social :

( @hookariagames.com and I made some animations too but she made A LOT of them)

Under it, 12 buildings, with funny shapes, we can build in the mine :
A hole with rocks and ores, a building with dices and cards, a tank filled with green poison, a tank filled with lava
an observatory, a sawmill, a cauldron filled with green poison, a volcano
a mole house, a building in the shape of a treasure chest, a tree with cursed gems, a giant dragon egg

Played Hold The Mine dรฉmo a few months ago and it was already really really fun.
Plus it has dwarves. Several.
Plus the devs behind are great.
Wishlisting the game would then be the smart move as it releases in 2 week !

For Hold The Mine, everything started 2 years ago.

I tried to take at least one screenshot/gif/video of the project every day from day one. I strongly recommend to do it on every project, it's always cool to watch the progress made

A screenshot of the game. The sky is a warm yellow, the ground is a bluish-green, mountains are beige-pink, and the gate of the mine are set on a big grey rock. 3 heroes stand in front of the gate, with a mole-shop next to them.
