just got to wave 93, from left to right i used 2 full columns of blue, 2 full columbs of red, 1 full column of purple, and one full column of green, didnt have to do much work till after round 60, replace 1 red for 1 purple when u have the purple pieces in your hand, at the later rounds its hard to keep a line of full green, just continue throwing bricks as fodder.
This game could really use a overlay button[hold] to speed up the process of building sstructures, the destroy tool could use adjusting to the centre of objects, accidentally deleting a laser is really annoying
strongly needs harder difficulties, if you can type faster than 60 words per second, you can summon a strong armored special before a monster gets near your base, too easy. Although the concept of your game is excellent, you just need to flesh it out some more
my rating went from a 5 to a 3, the random AI of the computer is so annoying, when silly strike targeting and other similar things make you loose a battle you should have easily won. you should at least be able to select a priority offensive and/or defensive card
tip for the last boss, if you fire a little bit after u fall of the previous screen you hit him on the way down, then you can jump up when the upper platform is about to dissapear and hit him twice asap, if there is two spiders on the ground you have to stay on the platforms, hope this helps so you all get to see the ending
