Since it's not serious to have more than 3 unfinished projects, I recently reworked on this one just after updating the SLUMS, and oh boy that was hard to get back to it.

So this update mostly focus on : core mechanics refinement, creation of a new (FURY™) system who spice up the thing a little, creation of a new rewarding and ranking system, creation of an "editing" mode, a ton of UI improvement, knights implementation finalization, optimization, and of course your dose of dopamine. Here we go for the changelog : 

The intro slightly changed, with a little extra added to it.

FURY system

The FURY system is a tentative to bring to the game a dynamic system who constantly scale on the player performance to give him a perpetual challenge and rewarding experience while (trying to) auto balance the game, cause I'm too lazy to do math. 

It is also made to not have to design a new mob with only +1HP x times. This mean I can now focus on creating new mobs archetype and letting the FURY system scale their lethality

HOW DOES IT WORK ? 

The game constantly keep track of your total DPS and the system will increase the FURY LVL by a specific number, and increase the mob lethality and earned gold by a certain %. Buying some S tier upgrades can also pump up the FURY, so be careful. Rebuilding walls and pushing the enemy further decrease the FURY LVL by 3. I will certainly had more depth to the system in the future.

The brand new UI, new skills and FURY system.

FULL CHANGE LIST :

• Now you will gain a rank and a gold bonus (a fair amount) according to how many damage has been taken during the last wave (showed at the end). Ranking from S+, S, A+, A, B, C and D. The ranking system take FURY into consideration, that's mean you will loose the same score if 2 exact ennemy of different LVL hit you, and the FURY gold mutiplier also apply on earned gold. Gold amount increased each wave.
• You can now edit the position of the units in the battlefield
• You can now press P for PAUSE
