"Relaxing" level 16 is unsolvable by logic alone. You get into this situation at the end where either pair of diagonals solve all clues: https://imgur.com/a/C0jW6 -- the only cells geometrically capable of discerning between them are the two 0-hearts on the lower corners, and since their only open cells are already next to filled ones they tell you nothing either.
When you complete a challenge level, please put us back into the challenge level list. As is, we have to navigate all the way back into the level select then go to the back for the levels we were already working on.
I think that workaround confirms my suspicion on the cause of the screen transition momentum loss. Your position is calculated per frame, but your acceleration is done on realtime DT. So when you jump up into a screen where eight dozen monsters load all at once, you get one slow frame where you lose half a second's worth of upward speed but only move one frame's worth. This is very bad practice -- you need to pick one timekeeping standard and stick with it or potentially game-breaking discrepancies like this crop up.
A workaround for the problem where loading a new screen kills your upward momentum. Before you fall back into the previous room, hit R to reset it. The assets are already loaded now, so when your momentum is reset you'll make the jump as intended.
The game in general is fun, but the square physics are kind of annoying in places, especially where you have to skip over an exit for a docstring. It seems completely arbitrary.
OK, so maybe that docstring wasn't the best part of the game ^^' Already changed! Thanks for Your constructive feedback. And congratulations on the perfect score! :D
So with the exception of "Level 1" with the bomb clipping through the ice, pretty much all of these X-is-impossible things come down to your momentum getting screwed with on screen transition if it doesn't load pretty much instantly. The effect seems to be pronounced with large numbers of objects.
"The Tour" is also impossible. Coming up from "Time Bomb" back into "The Monster", the spring from the screen below doesn't put you high enough to get to the first platform.
Echoing the broken "Inside the Mountain" comments. "So Nice - Do it Twice" in "Level 1" is also broken -- once the enemies are cleared, the fans give the bomb so much speed it clips right through the ice it's supposed to blow up.
The game is just way too prone to your dudes being morons -- failure to focus fire, using abilities the enemy is immune/resistant to when they have other options, etc. I feel like I'd enjoy it a lot more if I had literally any impact mid-combat besides a randomly targeted spell that most enemies will just walk away from before it hits.
You're not preventing up/down arrow presses from propagating off of the game and into the browser's scrollbar. The whole page will scroll if you hold up or down.
Very frequent stuttering (about once every 3-5 seconds) makes it nearly unplayable. In the space of each stutter, my box has cleared half the width of the arena and several bullets have come and gone without ever being seen. I'm on a Win10 desktop that regularly runs more intensive things than this, so I doubt it's insufficient hardware.
Could be depending of the browser you're using as well. I have tested on low end desktops as well so It should run smoothly! I recommend Chrome or Firefox for a good webGL compability. Also, you can disable functionalities in the option's menu.
