Try

gcc -o leveled.exe -g leveled.c titlelib.o sprite.o -lalleg

it seems gcc is taking laveled.exe as an object file to link with rather
tan the output file, and it complains about multiple definition of
everything. I've just testet it with a simple hello_world-like program:

bash$ gcc linea.c -g linea.exe
linea.exe(.text+0x1d8):crt0.s: multiple definition of `__exit'
e:/gcc/lib\crt0.o(.text+0x1d8):crt0.s: first defined here
linea.exe(.text+0x2c0):crt0.s: multiple definition of `__sbrk'
e:/gcc/lib\crt0.o(.text+0x2c0):crt0.s: first defined here
linea.exe(.text+0x4a4):crt0.s: multiple definition of
`_crt0_init_mcount'
e:/gcc/lib\crt0.o(.text+0x4a4):crt0.s: first defined here
linea.exe(.text+0x2d8):crt0.s: multiple definition of `__brk'
e:/gcc/lib\crt0.o(.text+0x2d8):crt0.s: first defined here
linea.exe(.text+0x0):crt0.s: multiple definition of `start'
e:/gcc/lib\crt0.o(.text+0x0):crt0.s: first defined here
linea.exe(.text+0x4c4):crt0.s: multiple definition of `main'
e:/gcc/tmp\ccdaaaaa:linea.c:4: first defined here

while gcc -o linea.exe -g linea.c works fine.

Hope this helps.
