If you have something to say to a dev - I'm here to listen

The boss fights seem to be imbalanced. There is a boss with two phases and in the second phase, you need to hit the boss 3 times in one turn to kill it, otherwise it regains the 2 units magical shield in the next turn. Of course, the boss has counterattack and insane attack range. Do I miss something? The mechanism of the game has a lot of potential....

- Most bosses are PAINFULLY hard. They spawn a lot of minion, they have armor which regenerates at the end of each turn, they have a boatload of health and/or they auto-attack back when your units attack. All of those really skew the action economy against you. Plus, even if you manage to beat the boss, you still have to get your convoy to the castle to finish the level. - Large maps are problematic. Most of the time, you'll be spawning your units at the left edge of the map, with a few exceptions of units...

Looks like I'm kinda unlucky with it. I've tried even restart multiple times, but Lich was never an option for the first round.

After pressed play to execute a turn, I got an Abort popup crash: ___________________________________________ ############################################################################################ ERROR in action number 1 of Step Event2 for object o_game: Unable to find instance for object index 0 at gml_Script_unit_mark_zones ############################################################################################ gml_Script_unit_mark_zones (line -1) gml_Object_o_game_Step_2...
