Sort of playable with caveats: - can't exit any of the games using touch only, - can't rotate internal screen without mouse/KB (at least virtual), - can't do multitouch stuff.

Clunky to play with touch controls (all the usual problems with seeing tooltips on hover) but possible.

It works on a basic level but there's no pause button, and some mechanics are tricky to do with touch only. Ball switching doesn't work by clicking top left corner but rather finger holding (like RMB)

Everything works flawlessly on touchscreen

Also available for tablets with cross-play support, no drawbacks found in touchscreen control in the Steam application in a full game.

Most of the game works great with touch controls, but your ultimate ability is sometimes difficult to activate using touch.

Works overall great with touch controls. Some minor issues with special abilities.

The game is built around touchscreens (Ported from smartphones? Notably, the game says 'tap' in the interface; everything is adapted to be played with simple taps.)

Works great with touch! NB: - minimize all windows before interacting, put them beside the game, or put the game always on top; - it doesn't bring up virtual KB when tapping Memo/To-do automatically.
