rad, though pretty tough. haven't finished it yet

This is fantastic! Great work, lovely puzzles :)

One of the best in my opinion. Good idea and good design!

Very nice! Clever puzzles, liked that it was made with puzzlescript too :)

Great job, very difficult but not frustrating. One of the better entries I've found!

I love the overall retro style of the game. Great work :)

Best puzzle game I have played so far in this LD! Nice job, it's hard to come up with original ideas on so little time

What a cool puzzle game. Totally awesome retro graphics!

My brain explodered!

Didn't quite understand the concept, But good job on the gfx

Very clever, and very nice pixel art. :)

Nice puzzle game! You made it give a funny look, and the puzzles are tough. I'm missing the theme though.

wow. Absolutely freaking brilliant. Clever mechanics and superb application of them. Well done, sir. Well done.

This is such a nice puzzle. Maybe its just my thing but designing puzzles for game jams is just so hard. You did an awesome job!

This is a really cool idea, very creative :)

fun puzzler, good job!

good concept, needs a little more clarity, or im hungover which could be the issue....

nice game play

Nice puzzle mechanics. A bit difficult.

Well made; I didn't get the idea at first but when I understood how the beams worked it was a pretty fun game.

That was really tricky, but fun. I'd not heard of Puzzlescript before - it looks interesting.

Seeing your lovely comments I had to give you a detailed one, so here:

I played your game twice, the first time I didn't know it's an LD game (you might want it to be written somewhere in future games).
It appears I skimmed the controls part, so I didn't see the undo and restart buttons (I did figure out that r is restart). Either blame me as a rash player, or have it in small letters on the screen.

Levels 1&2: The introduction of mechanics one by one is excellent!
I did not understand what dangerous means at first (to me? aren't they covered?) but the design of the second level forces you to witness the meaning which is good.

Level 3: Same as before, good introduction of the merge mechanic, with one nitpick. I didn't understand at first that it merges all adjacent parts on the map. I've found out later the hard way

Level 4&5: Easy overall.
Level 6: Lot's of moving, but not too hard
Level 7: At first it seemed easy, but then it took some thinking, a good level!
Level 8: The bloody +'s. I haven't managed to finish it the first time, but did on the second. To be honest, I really feared there might be another level, but seeing as this one was the last, its difficulty is appropriate.

Your graphic style is nice and works well with your game, the 'waves' are quite natural looking too.
Audio effects are alright, and I'd really have loved to hear some music with them.

Very good puzzle concept and design, well done!
