For being as cheap as a bag of chips this is quite an enjoyable game. Decently challenging and the playable characters are different enough to provide some interesting changes on repeated runs. Which you should replay this game at least twice due to its short length, but this also makes it almost like an arcade game with how quickly you can start up a new run and reach the end a short while later. That's honestly the best way to think of it, a more meticulous and slow paced arcade game with Mega Man like level design.
