Laser Temple is one of the most complete and cohesive submissions this year.
The four colour CGA palette is wonderful, and coupled with chip-style sounds and mysterious music, does a great job of communicating the feel of an ancient alien temple. The puzzle elements found within the temple are distinct, but also carry a sense of vagueness in a way that make their purposes feel like a mystery until they've been encountered.
Puzzle complexity ramps up nicely, but doesn't really progress into challenging territory, leaving most solutions easy to discover without moving a piece. I don't think this is a problem for a jam game, but a larger scale game could benefit from dead-end solutions and more temple elements that change/affect the puzzle layouts in ways that aren't identifiable until they're interacted with (for example, perhaps moving a totem onto a switch tile could make a new section of floor appear).
The story of a lost team of sentinels in need of rescue leading the player deep into an alien temple feels like an evocative start, and though I was a little disappointing to not see that expanded upon I don't think that really detracts from the game that's here. In a larger version of this game, it might be interesting to have narrative breaks along the way as you find evidence of Kisaka's team that give players a moment to think about what they've done, what happened to the people you're trying to rescue, and what all this alien temple stuff might mean (without removing the mystery, of course).
Another possible consideration would be to switch the colour palette from the cool cyan/purple dominated CGA palette to the warm red/green dominated palette to communicate progress deeper into the temple.
There are also a number of grammatical issues and typos in the text as well that would be worth looking into.
Laser Temple is one of my favourite submissions this year, and I'm looking forward to seeing where the project goes from here!
Thanks for submitting and best of luck with continued development :D
I'd also like to do a short interview with you for an article I'm writing on the 2018 Linux Game Jam. Shoot me an email via cheese@cheesetalks.net and I'll send you through some questions!
