Ambitious effort creating a 3D game within the timeframe, especially when creating all the models yourself! Unfortunately I had similar issues to others, I found that once the enemies saw me they wouldn't stop shooting (meaning I had a stream of bullets coming at me from off screen) and I had a bug where I placed the block character on a button, moved the other guy through and smashed some boulders then died. When I tried to switch back to the block character he was in space somewhere and I was unable to progress any further unfortunately.
It seems like a promising concept and I really liked the fact you added a minimap to the game which I could see being useful (and I don't think i've seen that in any of the game jam games i've played before!) Well done for tackling something new!
