Please add difficulty options I’m struggling to beat some levels and there’s straight up no checkpoints

Where can I find them and what do they reveal? https://steamuserimages-a.akamaihd.net/ugc/2474256892467866427/BE0F6BB8C1CBE58174F12536CFA26A8756097C5B/?imw=5000&imh=5000&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false

Is that true? Can't be!

Once you give it some time and upgrades you start getting the hang of it and feeling the difference between the turtles... And they're quite different actually. Still getting the hang of those "nunchucks out" techniques and Raphs fury mode. Leo is the most straightforward as usual. The game really is lacking a dedicated combat training area (the dojo missions can be repeated but will move time forward apparently) It also needs a better way to show which sequence of buttons does what. That gif on...

its musthave now - since there a very small amount of players who can use hotseat -_- cmon devs...
