Just played through it, had a lot of fun!
Beat the game with:
SummonMini OnTrigger
Explode OnAttack
SummonDummy OnSwap
Shock OnTileSwap
Heal OnWait
Cleave OnAttack
as well as another Shock and Cleave but I forgot what they were on. I enjoyed being able to 'program' my own powers, and figuring out how to fight opponents with interesting combinations of powers.
I think it might be worth implementing a summon limit, maybe 10 or so, cause as you can see with the above setup, the ground [and thus chromosomes] becomes hard to see very quickly :D
