Ironseed game packaging -- feedback wanted (ITP: #971924)

Before doing RFS, I'd be grateful if people are willing to look at
this packaging port of 1984 DOS science-fiction space game (somewhat
similar in gameplay to StarControl2 / Ur-Quan masters), and give me 
hints about what should be changed.

Thanks in advance!

 * Package name    : ironseed
   Version         : 0.2.7-1

 * Vcs             : https://salsa.debian.org/mnalis/ironseed

It builds those binary packages:

Alternatively, one can download the package with dget using this command:

  dget -x https://mentors.debian.net/debian/pool/main/i/ironseed/ironseed_0.2.7-1.dsc


I've already noted few Info-level lintian warnings on mentors.debian.net page 
which I'll attend to (I'm building/running on Buster, which has older lintian 
which does not have those).
