If you are good at the game you never lose because it doesn't get harder until you lose, otherwise great idea and use of the theme, the art is what it is, but trijam games dont usually have hollow knight art so yeah :)

It does get progressively harder, it just isn't as balanced as I'd like. It starts off spawning 1 "easy" 3 letter words every 3 seconds. At the 1 minute mark, it ads an additional spawner for 4-letter words every 4 seconds. Then at the 3 minute mark it starts spawning 5-6 letter words every 5 seconds. I find that once the "hard" words are spawning it's only a matter of time until I get overwhelmed.
After releasing a few game jam games that were just way too hard I've taken to always leaning towards making them easy. Especially if I don't have time for a real balance pass. After all, most players will only play a game jam game for about 5-10 minutes max, so they don't have time to get good at the game anyway.
