What the hell is this game

So a couple weeks ago, I hopped into Godot to experience it's pros and cons. At some point of my learning process, I had to find an incredibly basic project to make the process go on. This is the project. It has a single game loop which is:

-Enemies come => You beat them => You get some stat increments => Enemies shall come in greater size the next time => Enemies come-

With this core game loop, I was able to create this prototype in a couple days of active work. I'm happy with the outcome, though I'm aware that this is just a prototype. I just wanna drop the fact that I have used just a couple third party assets. I can even count that: The knight, the animations, the walls/environment/level up image. Since I'm kind of lazy nowadays, I didn't try to gather some assets to make the game actually look good, I just pasted some post processing to make it look stylized. Am I successful on that? NO. But is there something I can call prototype? YES.
