Tetramental
An elemental puzzle game in development, and a free web novel set at Tetramental Academy. The first chapters are free to read now.
03 · Game for kids
Cat Typing Forest
A free, cozy typing game for kids that runs in any browser. A cat hatches and grows up as your child learns to touch type, through 100+ lessons and mini-games. No ads, no accounts, nothing collected. I made it for my own kids.
