Looks good and sounds good.
Played the game 4 times didn't make it to the elevator once.
Here are somethings I thought about when playing the game...
Constructive feedback:
Player's grid based movement isn't satisfying.
This ends up worse when you see the bugs can move in any angle.
Why did I die? - Ok, my energy depletes (maybe signal this with sound or blinking)
The starting point isn't the elevator exit? - Then I died...
Which elevator is the exit, what does it look like? (I think it's the green one)
Had to search for it before going on to look for the crystal. (I think this take the fun out because instead of looking for something cool - the crystal - I have to look for the elevator first)
Maybe the elevator could be the starting point or near the starting point ...
Retrying takes a little too long so in this build so it helps build some frustation.
