My comic is not strictly story based, but I still have a good number of tropes in them:
Running gag - Jetpack powered by Apathy (now exclusive to holiday specials).
Breaking the Fourth Wall - I did a whole story arc on it, here's the start:
Planet of Steves - Quite fitting since all nonessential characters are named Steve or Alice.
Inexplicably Identical Individuals - Speaking of which, all non-main characters look the same.
Reused Character Design - It's actually quite painfully obvious how similar all my characters look and I do it on purpose. On the upside, there are only 4 main characters: one's a cat, one has horns, one has glasses, and the last one has nothing special, so there's not really a problem.
Here's the best panel with all of them I could find:
