Hi Dr. Slater,
Welcome to the forums!
I finished solving your demo pack. Here are my replays. This is not a bad attempt at a first pack so far. However, there are some peculiarities that I've noticed. For example, the color of the builder bricks don't match what they're normally for a tileset. On all levels, they all default to a dark brown-greyish color and anytime a lemming lays down a brick it's a purple-pinkish kind of color. I found this odd. Whereas, in fire tileset levels, the builder bricks should be blue, etc. Similarly, the color of the OWAs are not the default in level 7. I think they're supposed to be yellow? Certainly a much better color than what they are currently on the wall in that level. Maybe you did some theme mixing or something? I'm not sure.
Whereas for the 8 levels you currently have, definitely some great ideas/puzzles here. This demo seems to indicate that you are aware of the standard of not having time limits on levels unless they're to block backroutes. I certainly don't mind time limits, as I'm kind of a traditionalist when it comes to the game, as well as how I love numbers/math. However, there's absolutely no reason for them on the first 3 levels, especially since the RRs are locked and you're always guaranteed to finish on time.
In my opinion, level 5 was the hardest due to the very strict time limit. I kept running out of time on several earlier attempts that would had worked but they unfortunately take several seconds too long.
Interestingly, I thought level 2 was impossible, but turns out that I didn't go about the level correctly. It's extremely tight on the timing, although
I love how the miner is used just for delaying purposes until the exit unlocks and he can exit
I like the concept in level 3, but the execution is very annoying, particularly since the builders have to be pixel precise and on the dot. I would advise widening the spacing between the bars to make it clearer and also to provide some leeway in the skill assignments.
Among the non-timed levels, level 7 was my favorite
It was also a difficult level, and somehow I feel my solution isn't intended, especially since I have a builder leftover.
Finally, I'm almost certain that my solution to level 6 is a backroute, and somehow I feel my solution isn't quite intended in level 8 as well.
Once again, not a bad attempt at a first level pack and I look forward to seeing the full release of the entire pack in the future
This does raise a few questions, though.
How many ranks and how many levels per difficulty are you planning?
What exactly is this pack about? I know you already described a bit of it, but a more detailed description would be nice. It's great that you provided some pics of some levels that are/will be in the pack
These certainly help in possibly getting more people to play the pack. For examples, you can look at the level pack release topics on the NL levels board.
