This is seriously good! Addictive, too! I keep trying to get past where I left off! You weren't lying about it being insanely hard! xD
I don't mind the no-checkpoints or the fact that it is insanely hard, but there are a couple things I would suggest to add. NO, not checkpoints xD That defeats the purpose!!
First thing would be a death counter. Counts how many times you die.
Second would be a "Best Distance" sort of thing. Maybe on the bar on the top, put a marker of some sort where it is the furthest you've gotten. It'll make people more competitive and play this more, knowing that they can beat that!! This will make people go for the end instead of rage quitting.
Finally, this isn't something technical, but maybe the red triangles, instead of just triangles, maybe be something deadly from Minecraft? Like creepers or something? Just a thought. I didn't get very far in the game to be able to see all what was in there, but that's just a thought.
Anyways, great work!! Can use some tweaks in collisions but other than that, I love it! :)
Keep up the awesomeness, Rick! ^w^
