No worries, I almost exclusively played the Teenage mutant ninja turtles ones, it was done in Aseprite.
For bigger things like the intro drawings I work on paper first, scan it and draw on top of that layer with a tablet. For smaller sprites and animations I use to work directly on the app with the mouse.
I'm 100% doing more different types of games in the future, but for now, if you like tower deffense games I have another game playable on browser called "Toddler defense".
I started doing pixel art comics and recently jumped into games too, and comments like yours make me so happy. If there's any other question I can answer let me know 👾
