Hey I just tested your game with my 4yo daughter and haha wut... Straight to the boss? no story behind? And the name of the boss is LOOOOOOOOOOONG :P
Anyways, great attempt to create these mechanics! I still feel like there's much you guys could have done with the main character. There's no need to jump - and evading doesnt really evade... So beating the boss is a mix of monotonous and hard.... Like too short range,and he is op. :P
The game looked promising at first (specially the music) but after dying 12x times and just using a knife... Meh... That promise vaniashed pretty quickly.
The idea is great! I can imagine a longer game and flowing gameplay curve if you guys had more time to develop it further. But I guess thats what it is for a game jam...
We also did a dark souls - like game so take time to check it out!
P.D. kudos on doing it on 3d! That is lovely to see :3
