I liked the idea of it, but having to go back to the beginning every time you lose was quite frustrating. I did like the music a lot though. I ended up giving up on stage 3 or 4, where the key is on a platform but that platform wasn't an actual wall, which makes you fall down, and its really easy to die there when you think you are going to land safely.

Thank you for your review, we are well aware that it has some bugs (like that platform you mentioned) and that it's definitely not finalised yet (actually, there is a lot of work to do), but we will definitely fix it after the jam is over so every suggestion is welcome and we are thankfull for your review :)
I just have updated it once again, now it's written in MonoGame and works pretty well. Furthermore, gameplay is much better, way more intuitive and I fixed everything you have mentioned. There is level select option now, so now you can play where you left off after gamw over and there are no more platforms where you can fall through. There is more so feel free to give it a try ;) (if you want to). New version is Alpha 2.0.
