similarly to arch's comment my only complaint is it needs to have a reset game and it needs to be longer. i say it needs to be longer as in PLS CONTINUE THIS I LOVE THIS GAME SO MUCHHH :D
IM NOT EVEN A PUZZLE FAN, THIS HAS ME HOOKED! ANYWAYS onto my review
theres so few games on here that i am lost to find feedback on! this is one of them, let me walk you through the masterpiece of your own game for a second. you start out not knowing anything.
you're stuck in a room and a little green area and you don't know what to do. usually i would say "maybe a tutorial would be good" but i finally tried to run into a wall that was sticking out just enough. this felt really good, i have to compliment you on this! you introduced your game concept amazingly to where the player may get slightly annoyed trying to figure out how to make the blocks move properly but they figure it out just soon enough to where it feels absolutely amazing! you don't need a tutorial if you are this good at introducing a mechanic!
as i played i appreciated the simplistic art style, the blue tiles are really pretty to me and grew on me quite a bit! the green area where you push the boxes to blends in nicely with the blue tiles. the music as well tops it off giving it a calm and warm feeling almost. adding to that the sound effects as i move the blocks are like ear candy, they sound really nice and smooth. all this culminates in a calm fuzzy feeling while playing the game that is very hard to achieve when playing a puzzle game and it's very important as well!
furthering my experience, when i got to the boxes i was like "ooo a box!" you made a level introducing it very well! the next level after that was just the right step up of difficulty too! on the topic of levels, your level design was amazing throughout. i at first felt it to be almost mindless, like i was breezing through them. then it started getting harder, less mindless, more challenging. but just slow enough to where on the level right before you introduced the box mechanic it felt like i was ready for the challenge. it felt like i could do it!
this all being said, you have made an amazing game, an amazing project, an amazing experience. this being your first game jam is impressive to me. this game is simplistic but it takes that and makes it a fun and addicting experience that anyone could enjoy. even a person who doesn't often play puzzles like myself! good job on this project :)
