Does a lot of things really well. The possibility of death isn't so bad when there's a moderate healthbar to lower first, and it's actually fun to replay the stage perfectly after draining the energy bar down while still experimenting.
I really loved it at first, though it gets a bit tiring to play too many stages at once, and there's a bit of waiting when you need to move multiple character around, even if it is only in one screen. Pathfinding's flawed too, but bearable.
Definitely a lot more modern in feel than pretty much any other game from that time though.
