Thanks for playing again and for the useful feedback!
-For the level 1 to level 2 transition, I agree, forgot to fix it in the last patch but it is now more apparent since you can go faster. I should make the transition start earlier and be faster (like for the other level transitions)
-You probably had an issue with an invisible collider.. I couldn't reproduce it but for a bigger game I will definitely be more careful about those situations!
