discard works when you can't click... but too easy... the default deck is too weak and most guests can be defeated just by adding a lot of recruit/school/sorcerer and removing the weakest attack/build cards
and another... sometimes a quick down-up-down-up sequence will send you on the asphalt above the jumped-to car, rather than getting in it and running with nitro on
hmm, level 16 seems buggy, i did SENSE|0|RED, MEM|1|-1, PAL|1,2,-1,-1|1,8, L+=0 L-=1 R+=3 R-=-1 but the first time I tried it the bot looped. now I typed it in and it works...
also, save/load should be automatic once a level is solved. i had a nice solution for 14 but i lost it because I forgot to cut'n'paste it out of the game...
compared (obviously) to puzzle bubble, it lacks the ability to do tricks by bouncing against the wall. it's too easy to predict what the bubble will do.
