UNDERBOX

UNDERBOX is an endless survival boss rush fangame (a sandbox, kinda). Survive for as long as you can and try to beat your own highscore!

UNDERBOX is an UNDERTALE fangame, please play UNDERTALE before considering playing this game.

There are seven levels on total and each of them has a monster with different attack patterns. Try to unlock all of them!

Play as all soul colors! Also, you now have an ENERGY bar and with that you can RUN really fast to avoid projectiles!

The game has a list of achievements/challenges, beat all of them to... um... feel good about yourself...? I guess.

And that's it! Endless fun awaits for you in UNDERBOX!

But... There's something odd about this... Something just doesn't feel right...

!!IMPORTANT!!

HOW TO SAVE YOUR PROGRESS: Select the "Exit" option in the level selection menu, press the "up arrow" key until you select the star, then press the "Z" key to save the game. You know this has worked when you hear a sound effect.

Ps: you can press either "esc", "c" or "ctrl" to bring up the options or the pause menu (it depends if you are on a level or not). Also, you can use the pause menu to skip the darkness/maze sections.
