It's pretty fun when you get the hang of how the upgrades and such work. I kinda like how the game makes you do more quick thinking like with deciding which charges to sacrifice and choosing which upgrades to use. The problem is that the game doesn't give you a good explanation on how some things work and how the game actually doesn't have an ending since you can't progress after a certain point. Despite this I'd say that I'm fine calling this an actual sequel to the classic nostalgic game.
