Hey, Thanks for a detailed feedback! It is really helpfull when it comes to gaining experience.
Now that i actually played it, it is kinda boring to play. Crazy thing to say for a dev, but yeah. As i have said in a post above, we were delaying balancing and QA, because we didn't really realized the scope of a project and thought that we will manage.
Initially, we were planning to have all kinds of stuff: mini games during typing (like answering to phone calls, or using a fire extinguisher to deal with burning, etc), ingame shop to add a progression to the game among other things. We ended up creating the bare minimum for the typing system and "kitbashing" basic visual assets in 5 days, with last 2 being spent to finish the essential parts and some polish.
As for the texts themselves, i don't think that they need to be THAT short, but shortening them would definitely help. The game actually has shorter texts, which are 2 times shorter. but they appear at level 2 and 3, and only after finishing the long one.
When i was searching about average typing speed of people, i found out it was something like 200 symbols per minute. And at the moment i though "hmm, two hundrod", and my brain just didn't click and i thought it was 200 words. So, yeah.
