Thanks.
Yeah. There is potential for more complex levels even with current set of commands and conditions. For example, recursion. A concept which already works because of the way the 'CPU' it is implemented, but I haven't even touched it in level design. When combined with 'paint' commands and conditions, it is possible to create very interesting levels.
Since I got lots of positive feedback (not only from you on itch.io), I'll probably develop this further.
