I decided to update the design a little: warp zone (But this may change)

Health Bar (for monsters) (+ sprites for monsters that I managed to make (3 + hard mode)).

The chances of monsters appearing:

Normal: 80%

Hard mode: 20% (after lvl 10)

Battle system (This is how the battle system might look like)

Cuphead

Underfell Sans

Don't

New menu (test)

Core Frisk

Sans at the battle (remastered)

Clover
