I'm rating this based on the revised version and didn't play the original (if that's ok!). One quick note I have is that it was hard to get the game focused on the screen on the game page; it felt like I had to manually grab the scrollbar in order to get it right. Other than that (and it might be user error lol), IMO the presentation is excellent with the standouts to me being the audio (music, sound, and its balance) along with the smooth factor of the splash screen and the way the buttons change size when mousing over them. So satisfying!
It took me a few plays to "get it" but I enjoyed this action challenge and how the music suits it. I don't think lack of tutorialization hurts this game, but I do think the mushroom hitboxes are too large. I also keep forgetting what my score was when I get a game over because I'm so surprised when I lose. This surprise also speaks to your game being addicting and fun! Thanks for sharing this nice project.
