accept only integer type values for arguments

use [tick] for logo_start & logo_ending read

Looks fine to me! i just would change the description:
tick - 1/60th of a second
to:
tick -1 = 60 times per second
first one may confuse some non-english speakers

[Apaczer]

Hmm, then it should be "60 ticks per second" or "60 ticks=1 second". Regardless, semantically it should be left as is, I could just use ¹⁄₆₀ character.

yea i was about to wrote 60 times per second, but then "tick - 60 times per second" doesnt look very descriptive 😄, lets leave it as it (1/60th of a second), is nothing very relevant!
