This version adds some game mechanics, which not added to jam version due to lack of time

What's new?

Levels

• Increased ammount of gold to open the exit door
• Added transition to next level
• Increased difficulty based on level

Shop

Between levels you can spend your gold for healing or buying an upgrade, making your surviving a bit easier

Upgrades

From this version you can upgrade your character. For now there are 4 upgrades available:

• Convertion (heals you when you pick gold)
• Fast Recovery (reduces recharge time of oxygen after taking damage)
• Fast Breathing (reduces recharge time of oxygen to max)
• Strong Breathing (increasing the max of oxygen you have)

Other stuff

• Changed image of health
• Increased size of player (sprites and hitbox)

This post inspired by @noah-beckman question about how made the minimap in this game

So, let's start answering

First of all, the game zone is the matrix of tiles [N+2,N+2], where N - is dungeon size, so it makes easier to create level map. After the generation of dungeon I use loop [0..N+1,0..N+1] to create a level texture [N+2,N+2] pixels, which will be used later. Blue pixels shows walls and white - free space. Also I create a black fog of war texture with same size.

Next, the step-by-step explanation of map creation called every frame: 1. Copy level texture created earlier 2. Loop [0..N+1,0..N+1] to add info about exit and gas locations 3. Add the location of the player by transforming the coords with Mathf.Round function 4. Apply the changes for level texture copy 5. Loop [0..N+1,0..N+1] and calculate the distance between pixel and player coords. If it less than 5, set current pixel on fog or war texture to blank 6. Apply the changes for fog of war texture 7. Create blank texture [N+2,N+2] pixels 8. Loop [0..N+1,0..N+1] to fill created texture with combinig info of two previous textures. If fog of war pixel is black, add the black pixel, otherwise add the pixel from level with objects texture 9. Apply changes and transform to sprite 10. Show the sprite in UI

The image below represents how it works in game:

P.S: if the game got the 50 rating I'll post the explanation of dungeon generation algorithm

In this post I'll explain how the walls made in this game

The problem that I encountered is drawing the correct wall sprite depending on the neighboring walls cause of many variations of it. So how to avoid lots of these checks in code? Bits. Let's explain this one

Let's suppose we have to choose correct sprite in red-squared tile. At the beginning, we look at the state of neighbors (wall or not) and mark it as 1 or 0 as a bit. After that, we combine all bits to one number from top neighbor in clockwise direction. In this example it will be 01000000b = 64. The found number is a ID for sprite that we need to draw

Pluses

• constant time to find the correct sprite
• easy to debug
• easy to implement

Minuses

• need a 256 sprite sheet
• sprite repeating

What’s new?

Optimization

• Decreases amount of memory leaks. Previously, after playing 30 minutes, it shows "Out of memory" error. Hope it fixed now

Levels

• Added easter egg level. Hope you can find it :smile:

Interface

• Added heal and damage floating text above rogue
• Added skill description after buying it
• Breath bar works correctly. Previously, it shows only last 3 seconds

Balance

• Reduced cost for buying skills
• Skills cost depends on sum of obtained skill levels
• Skill "Strong Breathing" increment formula fixed

Buges

• Skill "Strong Breathing" couldn't be obtained from shop
• Upgrading skill to level 6 crashed the game

Others

• Rogue max movement speed is set to 1. Previously it could be 1.41 by moving diagonally
