Thank you very much for playing and I am glad you enjoyed it.
Yeah I had to use assets I found on itch, because we didn't have pixel artist on the team, but yeah they don't really fit together, that is true.
It is little bit strange not having a jump button/function. Sadly it originally had a jump function, but it was glitching way to much and I had to scrap it, to have time for other functions. From your description, the UI is certainly not in the right place. Thank you for telling me about it I will check it on and hopefully fix it as soon as possible.
I want to continue learning about 2D development and I will probably use this game for it, so I will add it there later in the development.
