Ironcast

A steampunk match-three roguelike.

France and England are at war, but to make things fun they are fighting using steampunk mecha and as the pilot of one of these it is up to you to go on missions to take out enemy armor and ultimately the boss... via tile matching. Base tiles give you either ammo, energy, coolant or repair and filling up your reserves let you do various things on your turn such as fire, power up shields, run, etc.

Still a large element of luck as usual.

In between missions you can upgrade your mechs systems and gain abilities through exp points but if you die, prepare to start from (almost) scratch. Yes, its a roguelike but the further in the campaign you go the more campaign unlocks you receive meaning you can start with different pilots, mechs and upgraded stats. For such a simple game I had quite a lot of fun with this one and actually do recommend it for idle or non-gamers as it is super simple, yet quite addictive. I also quite like the France boss theme so I'm scoring: two and a half shields out of five.

Insight: You can chain diagonally and always kill enemies if you can for their salvage (unless you are going to lose). Also, its worth spending to upgrade so that you last longer through the campaign. Make it to the boss and you'll probably have enough to unlock some campaign stuff even if you do get killed!
