I've finally uploaded version 1.1. It may still be buggy, so I'm looking for your feedback! From now on, I'll concentrate on bug fixes and optimizations, if applicable, and there probably won't be any new important features added in the near future.

Here are all the major changes:

- Fixed the steering. Now there's a "player inertia" slider in the options to adjust how fast it responds to pressing left and right.

- The fuel lasts for longer and is replenished a bit faster. However, the fuel pads spawn a bit less frequently.

- Fixed the bug in classic mode, where no terrain and objects would generate upon entering a stage, which number is a multitude of 20.

- Fixed the bug in CRT shader where blur would not be applied correctly in-game.

- Added guided bullets (toggleable), which move sideways along with the player, just like in the original River Raid.

- Added the classic fuel bar (toggleable), which is more similar to the original.

- Added windowed mode.

- Increased HP of the bosses.

- Made bosses optional.

- Changed the collision detection for the bullets, so you can destroy the fuel pad while flying over it.

- Added the option to customize controls

- Tweaked speed of some enemies.

- Reworked the 3D models of enemies, so they look less flat.

- Added some new sounds.

- Changed shooting sound of the tanks so it resembles the original.

- Simplified the tree placement algorithm. Now the positions of will be the same for each stage (except for islands, river banks and boss levels), but the actual tree models for each stage remain semi-random.

Known issues:

- The battleship sometimes shoots itself down for some reason. I still can't pinpoint the cause.

- The game can sometimes freeze during the flyover demo after Game Over. It's best to press 'Restart' or 'Quit' rather quickly.
