Seems like a good game. Keep up the good work. I teach 1st grade and I make educational games too.
I am teaching kindergarten during the day and in the afternoon I teach elementary kids at the moment. I am teaching in Korea but I've also taught in China and in the US (TX). Not my first gig at a kindergarten but all together I've only got 2+ years experience at this level. Most of my experience is teaching adults. Can I ask what you use to make your games? Do you code? I am using Gdevelop. It's a no-code game engine but I am thinking about learning JS so I can have more control over what I can do. I am currently interested in making a game where my students trace the letters with their fingers.
All my games are made with Game Maker Studio (1). I'm not much of a coder and use a lot of drag-and-drop functions. I self taught myself how to make games through years of trial and error. My games are very basic.
If you have a Windows 10 PC, at the Microsoft store, you can get a free Trace the Letter game called (ABC Kids-Tracing and Phonics) by RV AppStudios
