*cool* game.
i loved the story behind the game. its really fun.
here are more thoughts about it:
1. dont require knowing WASD and jump in order to get to the tutorial for WASD (that was the funniest bad tutorial ive ever seen). Put the controls on screen before the player ever has to touch a button.
2. there really needs to be an indication as to how many fountains need cooled before the door opens. Some UI (like 1/3 Fountains), an icon on the player, or even an indication on the door itself would have beenn ice.
3. The door should be automatic. The player should go through the door (when its open) by just going into it. They shouldn't have to press E to go through the door to the next level.
4. When Im standing still next to a wall and then jump, I should jump straight up and NOT be bounced away from the wall. This little wall bop mechanic was very frustrating. Honestly tho, it was fun to hop up a single wall, but there were several cases where the character should not wall jump against a wall.
5. Messing with things like speed up time and slow down speed is a very slippery slope. Its very easy to make a game thats unplayable because the very physics governing the character are constantly changing, making it near impossible for a player to complete a level. Luckily, this game was pretty safe in that no levels were too hard or required extremely concise inputs. So Id say you get away with messing with things you shouldnt... for now at least (please keep this in mind when making the post-jam version).
also, what is the ice cube's name?
music 8/10: great, but not Ori levels of great (8/10 is the highest im willing to give to a jam game)
art is mostly good. it could use more variation in the tile textures, but the animations were solid. The gate felt a little out of place style-wise, even when closed.
overall a pretty good jam entry.
