Other mode suggestions. Probably some of these should be unlockable:
- Special heroes. Heroes start with a specific ranged and weapon blueprint (i.e., in inventory, not in shop) and never receive further ranged/weapon blueprints. Some heroes also start with unique, re-purchasable blueprints, though such blueprints often have a higher cost after each purchase.
- Classic Hero (possibly part of special heroes, described above) - No blueprints are available ever.
- Blue spartan: Every kill changes the weapon into one which is based on the enemy's weapon. Probably a hassle to implement.
- Endless run - Camp is available once before the run starts. Player starts with a bunch of blueprints and essence. Timed waves are more frequent (i.e., waves which start even if not all enemies are defeated)
- Last stand - Spartan has only 1 health and cannot earn armor soul points, etc. Essence gain and blueprint gain are both doubled.
- No ranged - No ranged weapon/blueprints
- No melee - No melee weapon/blueprints. Ranged weapons with at least two charges hold half as many charges (rounding down), but charge twice as fast.
- Auto-fire - No melee. Ranged weapons charge faster, but also auto-fires. Great for those trying to play on a trackpad without dedicated buttons.
- Auto-fire 2 - Same as auto-fire, but every attack simultaneously fires a melee attack and a ranged attack.
- Survival - Killing an enemy causes more enemies to be summoned. Beating a level is time-based. Killing more enemies if still a good idea for essence and blueprints.
- Chaos - More/Smaller enemy parties (i.e., more distinct enemy types at once during each level).
- Double - Double enemies, essence, blueprints.
- Poor planner - Blueprint is emptied after every level.
- Tinder - After each level, two blueprints are available. Both are free, but player can only pick one (or can skip). Blueprint-related blueprints do not show up.
- No Healing - No health blueprints (also no armor, no soul points, etc.), but start with 3X health.
- Fun mode - Double essence, double blue prints, double health, heal 20HP between rounds.
- Duel mode - Only one enemy at a time, but enemies are far more dangerous. All enemies have a couple points of armor and some invincibility frames.
