huh those engines are a bit too heavy for jams! An advice of mine d' be: make your game run on browser! you will get rated much quicker that way! Of the 2 engines you said you know, unity can make browser games! So use that one! K'?
Hey!
Actually training to find a job, won't be able to find anything without using one of these two.
But I keep your advise about unity, might be a better idea :)
Thanks!
