The concept was great. This is a very basic intro level that I can see being expanded upon. I am using NVDA screen and I did struggle getting it to work well at first. I was using the built in jump to function which it did detect the main menu options, but it would only label the the boxes as a generic name, which made it difficult to know what the option was for. Using the mouse and hovering over text, I was able to fumble through the options and get the game started. (I am not use to using screen readers so the fact I got into the game was a bit of a miracle lol)
The game itself has a lot of promise. The audio feedback worked well, and the visual cues worked well when I blurred my vision, so it seems playable across any spectrum of vision impairment!
Good work and thanks for sharing your work. It would have been cool to see more levels added with the creature moving to different spaces after X amount of time.
