Hello!"vertical fever" looks like a creative and unique idea!
I'm browsing the site on my mobile device and noticed there are no on-screen controls, so I haven't been able to try the game yet. However, based on the gameplay mechanics, concept, and screenshots you've shared, it looks fantastic, so I've already given you a rating!
Actually, I develop and manage everything from my mobile phone, so unfortunately, I can't play and review other games right now.
Good luck with Jam!
