Thank you a lot for the review, we appreciate it a lot since it gives us experience to improve <3! About “bad things” 1, 2 and 3, we really didn't notice how the movement was annoying and fast. Maybe we got used to it by the time we finished doing it and didn't do anything about it. About the jump, we did it because we thought the levels weren't big enough, and having a jump button which lets you jump instantly felt like it was “easy”, so we added the delay as an added difficulty. Possibly it was too much since many players have complained, and we could've chosen a better alternative.
About 6, we really didn't notice the soft lock, perhaps the last minute changes messed up the code, we apologize :(. About 4, we planned on making that the distance where the characters ended up after the jumps and the spikes were the same, but the map didn't let us do it, so we left it like it is now.
About 5, I honestly don't see what you mean. If you see this message, could you please elaborate so we can see what's wrong?
Again, thanks a lot for commenting, it really helps!
