Mech Kaiju Battle Prototype

Concept jam link: https://itch.io/jam/greenlight-concept-jam/rate/2133018

What I have for the prototype phase:

At the moment, there are 8 moves created. The 8 hexagons are buttons for those moves:

Top row (left to right): 

1. "Pass":  To be used when player can't or won't do anything.
2. "Regular Movement"; 
3. "Quick Strike;
4. "Arm Block"
5. "Reactor Energy Burst"

Bottom row (left to right):

1. "Reactor Energy Blast"
   
2. "Energy Priority: None"
   
3. "Energy Priority: Repair"
   

Name	Move type	Description	Priority (0-5) (slowest-fastest)	Range	Target	Requirements	Main effects	Additional effect
Pass	Movement	To be used when player can't or won't do anything.	5	0	Grid panel; 0 subsystems	0% energy cost	Passes current turn for player.	None
Regular Movement	Movement	Move forward or backward 1 tile	2	1	Grid panel; unoccupied panel next to player	2% energy cost;  Leg subsystems	Move backward or forward 1 tile	None
Quick Strike	Attack	Fast, but weak physical strike.	3	1	Opponent; 1 subsystem	8% energy cost;  At least 1 arm subsystem	5% target subsystem's health removed.	Can cancel out opponent's slower attack via flinching (unless opponent has hyperarmour).
Arm Block	Defense	Raises arms to defend, reducing incoming damage below certain threshold. If threshold exceeded, damage is still applied and you will be knockbacked.	4	0	Self; Head, Chest, Arms subsystems	4% energy cost;  At least 1 arm subsystem	If incoming damage is equal or below damage threshold, reduce incoming damage by 30%.	If incoming damage is above threshold, damage is not negated and player is pushed back if possible.
Reactor Energy Burst	Attack	Open chest plating to fire a large burst of energy from chest reactor. However, chest becomes vulnerable to damage.	1	3	Opponent; 1 subsystem	18% energy cost;  Chest subsystem	On hit, 20% target subsystem health removed.	During the turn this is used, if player chest subsystem receives damage, the received damage is increased by 50%.
Reactor Energy Blast	Attack	Brace and overclock chest reactor to unleash a devastating blast of energy. However, chest becomes extremely vulnerable to damage.	0	5	Opponent; All subsystems	50% energy cost;  Chest subsystem Leg subsystem	On hit, 40% target subsystem health removed.	During the turn this is used, if player chest subsystem receives damage, the received damage is increased by 250%.
Energy Priority: None	Buff	Set no energy priority. All Energy Priority effects are removed, and 100% energy generation is sent to the energy pool.	4	0	Self; 0 subsystems	0% energy cost;  Head subsystem	User will get 100% of the energy generated at the end of the turn in the energy pool.	This is a passive mode, and will remain applied until another passive is enabled.
Energy Priority: Repair	Buff	Enable passive repair system. Divert 20% of generated energy to repair 10% of all active subsystems each turn that this is active.	4	0	Self; 0 subsystems	0% energy cost;  Head subsystem	After each turn, all active subsystems recover 10% damage. Maximum generated energy is reduced by 20%.	This is a passive mode, and will remain applied until another passive is enabled.

There's no UI feedback of any sort. Any indication of attacks can only be found in the console. The attack buttons do send off the selected move for the "action resolution" part, but the damage isn't being applied properly. 

Minor Update: The damage values now update correctly. I missed a negative multiplier before using it to update the health and UI i.e. a punch from a multi-tonne mech/kaiju would be healing the recipient instead of inflicting damage.
