I thought this was an adorable little first game. I got all three endings, starting with the third, then the first, then had to twiddle around a bit to find ending 2, which is a LOT like ending 1.
There is some decent writing in this! (Ostensibly, allegedly, if you're feeling generous AND you squint, I write games ""professionally"", and have done for well over a decade now.)
I noticed the humor. It might be a good idea rewriting it again but completely dead straight serious, as an exercise. Either that and/or coming up with a "good" ending.
But my final comment is this: a tennis jam vaporizing a Labrador-sized cockroach into green goo? Dubious. Have you ever squashed a real cockroach or really any substantial bug? I'm not saying you can't kill one in one half-decent hit with a shoe or a rolled up magazine or whatever, but they definitely leave a surprisingly intact corpse behind. They are unpleasantly crunchy.
