Hello! I liked your demo, it has good potential to be a great game though I would suggest a small tutorial to ease the player into the game and maybe a bit more diversity on the backgrounds. Aside from that you've made a good start and I wish you like in this and your future projects! I made a let's play of your game here-
Hi Miss Blue... Woww! I'm really glad you played my demo! Thank you for your time doing this video and your feedback, this means a lot for me, specially now.
About the game, unfortunately you played a bit outdated version, the new one has gameplay fixes at the 2nd level and also that tutorial which I saw how much you needed in the video haha! I was laughing as crazy when you tried and failed so many times :D sorry for some stressful moments I saw that shouldn't have happened, definitely will fix those.
About the backgrounds, that's on my bucket list, after I finish all the game mechanics I have in mind, I will focus on aesthetics (there are actually some examples about what I have in mind for aesthetics in the landing page)
Again, thank you for playing and hope you play it in the future with or without video ;)
Cheers
