Hi, thanks for playing, your feedback and for soldiering on through to the end despite the bugs! Seems like the new build I uploaded wasn't quite watertight, so I've reverted to the previous stable version for now and will patch it asap, thanks for letting me know.
The blocks you encountered can be blown up with bombs, so if you are standing next to one select the bomb from your inventory and it will blow it to bits and clear your path, I probably need to make this a little clearer though.
Glad you enjoyed overall though, I will keep going with this though the bootcamp, best of luck with your gamedev also!
