Impact Bug

Yup, looks like a valid bug. I'm running a Google/LG Nexus 5 with Android 6.0.1. Happens for me too.

You should mention this level in a forum post under "Bugs and Feature requests."

@Propesyonal Unfortunately, unlike other bugs that we have adopted into exploits, this one cannot be accomplished consistently, hence it may remain as a bug observation. For example, everyone knows that something needs to touch the win (end button) to trigger it and complete the level. In this case nothing is touching the win and even if a player could notice the potential to use a slider near a win block in just this exact configuration, how many times is this player supposed to try before realizing that the level creator intended some more traditional way to complete the level.

In my opinion, this bug should be more of an alert to level creators to avoid rather than take advantage of and put the player in an illogical and unexplainable situation. We have a huge repertoire of consistent and explainable exploits now that level creators can use and experiment with that will keep Mekorama far from boring for quite some time.
