3. Tools have a 1 in 32 chance of breaking when used. This would also require removing the restriction of not being able to buy more than 1 of each tool from shops. I would also like, if possible, for the Chain Saw to be exempted from this, since it is the only unique tool not acquired from shops.

Don't know about making the tools break, but removing the buy restriction is easy enough.

Code:

Invoke buy order menu if justified
C3/B7E6:    20C2BF      JSR $BFC2      ; Selected item
C3/B7E9:    202183      JSR $8321      ; Compute index
C3/B7EC:    AE3421      LDX $2134      ; Load it
C3/B7EF:    BF0050D8    LDA $D85000,X  ; Properties
C3/B7F3:    2907        AND #$07       ; Tool?
C3/B7F5:    D013        BNE $B80A      ; Branch if not
C3/B7F7:    2092BC      JSR $BC92      ; Define $64
C3/B7FA:    A564        LDA $64        ; Owning none?
C3/B7FC:    F00C        BEQ $B80A      ; Test GP if so
C3/B7FE:    20C00E      JSR $0EC0      ; Play buzzer
C3/B801:    A0F5C3      LDY #$C3F5     ; Text pointer
C3/B804:    20F902      JSR $02F9      ; Draw excuse
C3/B807:    4C7DB8      JMP $B87D      ; Set to exit

Just JMP $B80A unconditionally instead of checking if it's a tool.
