Time Break Mode: A mode that will test the player's patience and skill. Cracks can appear in any game mode and even in the lobby. In this mode, only 3 units (and a farm) can be taken. These cracks may have specific elements per map and will grant unique rewards, with a 5% chance of containing a secret character.
For example:
[Hell City (inspired by Solo Leveling's Demon Tower)]:
Units that can be buffed: Units from the same series or anime
Objective: Defeat 5,000 enemies to complete the level
My goal with this idea is to break away from the monotony of Tower Defense games, where towers automatically defeat all enemies. I want to introduce clear objectives within the cracks, making the game more dynamic and connected to the series/anime universe. These cracks can feature challenging missions, like Hell City, which tie directly to their respective series.
(I'm not sure if I conveyed my idea exactly as I intended, but I hope I did a good job).
