My first puzzlescript game! Pretty simple concept, but I think could be fleshed out a bit...
Push the specified numbers onto the grey tiles to clear the level. You may need to CRONCH those numbers a bit first. Do this by pushing two numbers together, which will combine them into a new number by taking the difference of the two (i.e. 5 and 3 become 2). Cronching the same two numbers will destroy both (since it equals zero).
Let me know what you think in the comments ^_^ I've just recently started to get back into game design. Bigger more ambitious projects on the way!
