There's also a physick that gives you infinite mana for a couple of seconds (don't know exactly how long it lasts though), super useful to keep laser beam of deth running for longer.
Shredder's Revenge wasn't on my radar until recently (it looks great!) but I can't wait for the collection. Those NES games were my childhood. It's gonna be fun replaying them (and playing those I missed out on like Turtles in Time).
I hadn't really been following this game, but that gameplay looks so fucking good. They really nailed the "what you remember 16-bit looking like" aesthetic.
