Hello.
The changes on the strategic map are ok, but they require tweaking in the form of a special mission where sometimes we defend our agent and sometimes we want to kill a human alien agent. Another element is too little pressure on the UFO side. The idea of limiting tactical missions by losing OP points is cool. But in the current 5.7 system, you can improve the MIG-31 and beat the game. Withdrawing the level 2 autopsy is a mistake. More UFOs are needed. This is supposed to be a vase of 3 terorrsaits should be on Ra, so you need to have at least 3 teams to fight. Milestone 4, the UFO problem was better solved. In M5. 7 is boring. I have time for research, building new equipment for soldiers, and from mission to mission my team can heal to 100%. Boredom. Mission 1 on the orbital laser should be repeated as long as, for example, we do not obtain 50 alien intelligence data. So that the player has to send soldiers every few days to prevent shelling. Please add mission type two on the laser. Let them kill the engineers and mechanics who repair the laser. Their defenders should be these robots. Add a third level. E.g. Purple/orange. Currently, mission 2 is cool, but the eternal one must have some bodyguards from 4 caches. And some kind of shield generator itself, which gives him 200 hp of shield. Some armor with 50 HP and density of 30. The last mission of the game. Simple boredom. In the last mission some special alien version.
I have an urgent request to diversify the types of weapons. For example, each type of weapon should have distinctive functions. E.g. Lower shot cost. Greater range, armor penetration, greater accuracy, etc.
Colosus armor requires additional research and upgrades. E.g. It would be nice if there was a dedicated first aid kit for him. Some kind of targeting system etc. Research dedicated to these types of weapons, e.g. heavy machine gun, for example rotary cannon. Plasma cannon, etc. There is a great opportunity that after the discovery of the Colsus anti-gravity drive, anti-gravity armor and backpacks could levitate in the air like in UFO 1. Who doesn't want to have a flying suit like in UFO 1.
How to limit the excessive use of Colosuc Mk2 by price, production time, and the amount of materials used. And to produce new armor between mk1 and mk2. Its repair should cost as much as the damaged Mars. Add night vision and thermal vision. Let there be synergy between the flare and the night vision.
Apart from these comments, I think that your game has unlimited potential and you can improve various elements over the years. I'm waiting for more. Don't be afraid to experiment because the idea of having additional tasks on a strategic map is great!!!
