Disclaimer! The actual game will be released in winter 2018. No promises, though. It will not be canonically tied to the first two, and will be designed in a more "Bionicle Heroes" style of gameplay, with more "machinery" and boss fight strategies. In other words, less repetition. Speaking of which, here's a small mechanics preview. Use the arrow keys to move around and press space to shoot. You can double jump at the expense of the inability to shoot, as you cannot focus the weapon whilst flipping. (I'm still working on the double jump sensitivity, so until then, you've been warned.) Use the number keys 1-6 to select an element, and use the slider to upgrade the weapon to any level. In the final version, different elements will feature different shooting abilities, and the Toa themselves will feature different speed and jump abilities. The soundtrack will feature multiple Bionicle Heroes tracks from the NDS and GBA versions of the game, as well as a few preliminary tracks, like the one currently playing.
