mouse-only possible?

[MercxHaze]

the sseth review forever ago made this look really appealing and another video brought this back into my attention. i moved some time ago and my pc broke in the mail and im broke so ive just been playing games on my microsoft surface lol but its keyboard also broke and i only have 1 usb port. ive been playing darkest dungeon and slay the spire comfortably with just the mouse and was wondering if this game was feasible mouse only. i have my 2 programmable side buttons set to esc and shift for DD which are the only keys needed for that game so if it only needs like 1 keyboard input im ok. before i buy do you guys think it would be easy to play mouse only?

it should be if you can bind space and esc
