Hi man!
It's looking better than when I last saw it
Great job.
If this is a commercial game then definetely go 2.5D.
3D is waaay easier to animate and if you only have yourself and a few others then it's much more feasible and cost effective to go 2.5D rather than 2D without sacrificing gameplay length. Only relatively big studios like Daedalic can afford to do full 2D.
That's just talking from my experience though.
Looking forward to it
Cheers,
Myles Blasonato.
