NIce game, as said before i also encountered one of the classic physics engine issues and that is walls are very sticky. The last round was very challenging for me but i made it to the end. Well done.
If i could change anything i would have a bit less airtime for the jumps it made it a bit harder
Sorry meant to reply sooner but totally forgot
This is the first place i encountered that bug, al you need is to jump and keep pushing forward. However how to solve it not sure as it does not happen everywhere it might just be the collisions shape of the boxes ontop of eachother what causes it
When tying to reproduce this i did encounter an another bug, if you jump over the door (in at least the first level) you jump out of the level and have to wait till the time runs out.
