I never expected anyone would finish wall jump tutorial without ever acknowledging it even exists. That would actually be funny if not for the final result. I have to bulletproof the tutorial.
As for enemy projectiles blocking yours my intention was to add some dynamics - it encourages not standing in place and shooting, and encorages switching targets. It also foreshadows projectiles hitting each other which is used for defense later on.
There's no delay on jump btw, it's all animation making it look like a jump with windup. I never thought it would be received kinda negatively.
Thanks for playing. Yesterday I was reviewing up to the middle of the night, so I know the feel.
