I'm so glad you understand the vision! This game came down to the wire on a lot of things. The cannons were implemented very early on, but their functionality was left until very late. The wall wasn't implemented until hours before shipping. It TOTALLY was the plan to have the ship be oil-slick'd with particle effects, but it wasn't my responsibility and it just never got done. Somewhere down the line I may try to get the game into a more finished state, but for now that's the rub unfortunately. Thankfully, speed upgrades level 3 and above let you start fast enough to go right through it if I recall correctly. Thank you so much for playing!
