This is pretty fun and good concept.
My only complaint is - when you have players select their action bar, make them look like buttons. I was really confused on how to select actions for my action bar. And the shoot action wasn't obvious at all.
But, the concept is fun and gameplay is fun.
I encountered a bug, I went to the timed block which would turn into an obstacle block, and then pushed it forward
but when the timer ran out, since i was standing in position where block originally was, I was no longer able to move in any direction.
Otherwise, that's the only bug I encountered.
Well done completing your first game.
