Every anime has its Hot Tub Episode sooner or later. Makes sense to start with that.
For a fallback project, this is more than respectable. There's enough narrative here to make me interested in the characters, and I appreciated how you have to pay attention to Kilhn's reactions.
I noticed a few typos here and there, but they were fairly small, things like "haven't been able too afford" (with one "o" too many in "to") and "shity" (with one "t" too few.) That's probably to be expected from something made in three days.
