Very good

I wish I could make games like this! Hope you win!

nice job, this is a really good game :D its very creative! i know it had been said before, but a sanbox mode would be awesome

Just finished. Reaaaally good! I think it's my favorite now, it's so satisfaying to see it working and it just looks good. Had lot of fun!!

Very cool puzzle game :D
Just balanced as it should be,  Big GG for the level design! I really just loved it !

This was a really fun puzzle game! I managed to beat every level except for level 11. Spent like 15 minutes on just that level and got stuck before moving on to all the others. Smart idea to add a level selector in case anyone got stuck so they could continue. 

The level design was really fun, post processing and art have a great minimalistic look. I have no criticisms, well done :) I like it a lot

great game! before i give any criticism, let me say this is one of the most creative puzzling ideas i have seen in awhile. very fun and satisfying, so know that you did a great job. here's where i think you can improve:

i came here from your video and let me just say i personally prefer the original, minimal art you used to the pixel graphics in the game. i also think this game is in dire need of some level music. as for the levels, they are fun, but need some balancing. there are definitely random difficulty spikes (where levels in the middle are harder than the last few levels) and also are some holes in certain levels, meaning that the level design is open enough to allow for multiple solutions. now, multiple solutions is not a bad thing, but if the player can just sort of mess around until they flood the screen, it takes some of the skill out of the problem solving, and makes the victory feel less satisfying. but these critiques are all mostly fine-tuning concerns and given the 48 hour time crunch, you turned out an awesome game. good work!

theres no sandbox :(

Nice feel Sam! I like the post processing pass on the top. I'll add my voice to those who want sandbox mode!

Very neat game, though I feel like the level difficulty is unbalanced. Some levels make me think I have no idea what to do, some levels are just fooling around until I get a tumour that floods the entire level (though those moments are somewhat fun, if not very puzzly). Maybe this would work as more of a sandbox or a zach-like optimization game rather than a classical puzzle.

Another note: The art is not bad but I felt the pixel shading was messy and made the game feel poorly drawn (there's not enough pixels to do random dithering), your original sterile vector graphics (as seen in your video) weren't so bad this kind of game. Personally I'd stick with the pixel art but I'd use much simpler maybe even single colour blocks with symbols painted as is.

love it
