Any control or technical requirements? (controller, number of players, etc.)
Minimum 2 players, up to 4. Up to 2 players can play on the same keyboard with WASD + Space and with arrow keys + right ctrl.
Additional players will require controllers (or if you have enough USB ports or use parsec, everyone can be on their own controller). Controllers should use the left joystick and the A button (or its equivalent.
The only controls (in game as well as in the menus) are up, down, left, right, and the confirm button. Double tap the confirm button to use an item.

Please note any known bugs or unfinished content to be aware of
Sometimes audio doesn't work in the WebGL build so downloading the Windows build would be preferred. Sometimes joystick input can be a little finnicky. On very rare occasions, when the game ends during overtime, the results screen will continue to fill with lava, but this does not affect the ability to start a new game.
