Hi there, cool to see you made your first game, good job!
I like the idea of shrinking horizontally and vertically, felt like a unique mechanic. Good job on the main menu too, looks like it fits the type of game you were trying to create. The background and its animations while playing looks nice, I think I liked that the most about the overall experience.
The biggest achievement is that you finished your first game, that's really really awesome! You should celebrate, it only gets better from here, my fellow game developer!
Oh by the way, I submitted the game Arachnophobia, just thought it was funny that we both came up with a phobia-ish name for our games :)
