Pretty fun game! Although, some aspects were a little confusing. I felt like the main objective wasn't too clear. It didn't take long for me to figure out what to do, but maybe add a tutorial or a controls menu or something like that. Also quite the interesting take on the theme, I wouldn't have thought of the player being a tower. It was also interesting that you fall upwards instead of downwards. Makes for some fun gameplay! Something I found is that most, if not all of the levels could be beaten by just keeping to the side and having somewhat decent timing. So maybe add a bit of a difficulty curve in the future? Like maybe more/harder enemies? Unfortunately, the end screen seem to not have worked. All I saw was a black screen with some music in the background. I was also confused on what the yellow heart did, as it seemed to have no effect when I picked it up. Overall, it's a pretty fun and unique concept!
