Hey.
I have some feedback.
Please, ADD A FULL-SCREEN BUTTON. Why? Your game uses the steering button on the mouse on a Web game. This can make the page go down. Furthermore playing games on fullscreen is just nice. Pretty sure that itch.io has a built-in fullscreen button on the game settings.
Additionally, sorry but I did not like the blob thing and some SFXs or music would be nice.
Also, thanks for making it so that the boss wouldn't start completely over when I died.
Lastly, please don't make the game start over right after I win. I like to finish games and take a screenshot of the win-screen but I can't if you just start over. Luckily, I could make a clip out of it: https://clips.twitch.tv/StormyThoughtfulMarrowDAESuppy-Dj2qovKZZLY2HKDo
