Hello,
My game is far from complete, but I wanted to share what I have done using RPGJS to let you know that it is a great tool.
Here is a demo: https://game.chylo.pl/
(The lowest price cloud machine, so can be laggy).
Move: WSAD, Attack: C, skill: J, Inventory: I, equip/unequip item: mouse double click
And video in the case when the demo is down:
