Hi Delak, this should certainly be possible using the toolkit. As a matter of fact the actual developers behind Pool of Radiance are currently using my toolkit to create a prototype for their upcoming game inspired by their classic titles: In the News | TSI Games
I have experimented a bit with including first person movement on a grid and it should not be that hard to implement. You would of course need to have decent knowledge of blueprints to implement this, but I’ll also do my best to help.
