Thank you very much for trying out my game and posting the stream of playing it. I will take that into consideration to reduce the difficulty. It was not my intention for the player to beat it the first time. They will have to get upgrades to get further on.
For cheesing the game by just running around the boarder, I was hoping to avoid that by incentivizing the player to get into the middle of the action to pick up experience points. Hence why you did not level up. I might add environmental hazards or new enemy logic to prevent that.
