I don't know how you do it, but every single one of your minimalist rpgs is absolutely incredible (even more so with that difficult expansion you always sneak out). While Three Goblets had really good pixel art, this game's music and art direction were just perfect for me. You've inspired me to try a side project in game development, and I can't wait to see what you make next.
I am currently on level 13 (Volcano). Some of my discoveries:
1) Combining 5 or more of the same block results in an instant level 2.
2) You can manually grab blocks out of the queue by clicking on them.
3) It seems like the ideal strategy is not the highly suggested 'stack a single type in a column'. You actually want a partition of completed blocks and behind that a 'factory' of developing blocks. Your development section should be abusing the 5 block trick in stacks so that you can insert the 5th block once you find it. A good single sided level development will look like this:
c_cd_dyyyw
c_cd_dyyyw
a_ab_byyyw
a_ab_byyyw
Where a,b,c,d are level 0 blocks and a,b,c,d are unique blocks, y are blocks level 2+, and w are any level of wall blocks. Stack higher as you wait for blocks to finish your developing stacks. Move your completed blocks to the complete wall and repeat the process. Wall blocks should be placed in that front line as soon as possible, ignoring the 'factory' area.
