To play Towards Tandemera you need some way to keep track of HP. This can be done with these super cool custom printed tokens and dials. But these are very easily replaced with just regular dice.

If you decide to buy these components from the Game Crafter, it's recommended to do so directly from the part shop, and only use the component list from this "game" as a refference. If you buy directly from here you'll pay extra for the listing price.

Things you'll need:

Enemy HP can go as high as 99: You need a single method of counting this high. The component upgrade box uses a dual dial for this, but you can also use two 10-sided dice.

Morale can go as high as 20: You need a single method of counting this high. The component upgrade box uses a dual dial fo this, but you can also use a single 20-sided dice.

Ally and minion HP can technically go as high as 20, but generally won't surpass 12. Multiple allies and minions can be on the field at the same time, so you'll need a method to keep track of roughly a maximum of 10 of them. The component upgrade box uses tokens for this, but you can also just use six-sided dice. Spindown dice also work great, if you have those.

Finally, some allies and minions have special countdown abilities, that activate only once, the first time they get ready. You need some way to keep track of which countdown abilities haven't been used yet. The component upgrade box uses tokens for this, but you can also use about anything that fits on a poker card. Winks have been listed here, which are the cheapest tokens I could find in the Part Shop. Again, it's recommended to buy directly from there rather than here.

You only need a single set of HP trackers, regardless of how many boxes you buy

This goes for both these dice or the component upgrade box.
