Ah its a shame You got stuck, I was so careful to never allow it... F11 should respawn You btw (see description). I think I found the place, I was lowering the jump height, and didn't test that part again. Bummer eh.
2, 3. Yeah... should be done, sorry. I really underestimated the efford a 3d game requires honestly. Just because there are sometimes easy solutions doesn't mean its quick to be done eh. I will fix that. And You guessed right, its 3 seconds. 2 seconds later another bomb will jump out.
4. Then we have to agree to disagree;) I really don't like maps everywhere, I prefer a solution where all graphics look more distinct. But its harder to pull off so... I've made characters that should point you to a place where you should go/what you should do next. Its not crystal clear though.
If I would've shown you the map, You would realize that the maps are actually 2-4 circles and that's it;) The design is quite simple, though for sure its a bit confusing when watching from inside.
It could be done better for sure of course. Thanks for playing!
