Madcap Mosaic is a fantastic little turn based game. It may look either overwhelming or overly simplistic at a glance, but there's a lot of depth to it once you start getting familiar with all the different possible tile types.

You start each run with a pretty standard board of tiles, which you move around each turn trying to collect enough defense to block the enemy's attack and enough power to deal damage to them, whittling them down until you win and move on to the next fight. Each fight you get to pick two of the tiles on your board to replace with others from a sprawling randomized skill tree of sorts, giving your board more complex options, and hopefully playing into a strong overall 'build.' Maybe you've gotten a few tiles that go off 'on reveal' early, and want to shoot for Clairvoyance so you can pop them quickly and en masse, or maybe you're worried about being able to move around fast enough to deal with the spider or robot enemies, and want to work towards tiles that give you extra moves, let you teleport, or activate or drain tiles at a distance. The traits and unrevealed tiles wind up making each run feel substantially different without necessarily seeming like guaranteed wins or losses.

This would be a fantastic game for travel on a laptop or Steam Deck, and if you liked Desktop Dungeons or Into the Breach, give the demo a shot and see how you like it. I recommend it even at full price.
