4/5 - what they said^^
+1 if:
- option to increase gamespeed for lover lvls
- rewards for killing spree of faces -> coinmagnet?
- rewards for coinspree -> increased value?
- update option: increase starting-lvl of on upgrade tree -> start with 2, 3, 4, ... balls
- infinity modus with other faces (one that does not move, can only be killed with balls and spawns blue bricks / faces), other bricks (exploding when hit with ball/shot or freezes (makes surrounding stuff blue if hit with wrong thing), SCORES -> HIGHSCORES
- AWARDS -> REWARS for ingame (i.e. timefreezer once per run on space, while balls move...)
- change ending: bit lame
you could show (as hint) what is a possible element, so we must find out how to create it.
loved the accidental combinations like Human + Fire = Corpse...
