Thank you for the comment!
The mouse bug was very difficult to fix because it is linked to how the browser sends mouse events, we will hopefully fix it for our next jam! Thank you for lettings us know that this is more annoying than expected.
We didn’t have an experienced Game designer in our game (this is our teams second game jam) and I think that it is noticeable in how the levels were created. As a team of developers, we mainly focused on adding features instead of implementing them well. A lesson well learned ^^’
