I streamed this game on twitch yesterday and received nothing but positive feedback. It's amazingly fun to play, I don't even care that I continually die and have to start over.
I'd be careful with checkpoints/savepoints. It really comes down to how long a playthrough might take; if you are playing for hours and you're only at the midpoint then yes you need a savepoint. However if the game could be played through in say 30 mins a savepoint might make it too easy. It's all about the time it would take in my opinion.
