Thank you so much for featuring our game!
It was great to see what you found fun, intuitive and challenging. It was also valuable for us to see what you found confusing or unclear.
The cannon and sprinting features are two common examples we saw play testers and other jam participants have trouble with.
For example, the cannon works like any other hazard. It is interactive only when it has a call out bubble above or in the sidebar. But I guess players got excited by the idea of firing a cannon so tried to use it even when it is idle.
If we had time to spare during the jam we would have definitely improved the user experience and removed such ambiguities.
