Since this is under development, there are some known bugs and issues.
We are currently aware of the following:

Wall jump might feel a bit funky and is getting a re-work.
You can get stuck in animation when you interact with the Rival.
You can "climb" walls.
Tutorial text will be shown multiple times.
Enemies can "fly" if you stay above them.

If you find something else, feel free to leave a descriptive comment, so we can take a look at it.
