Ok, now I've got far enough in the game that the spikes can be selected as one of my powers at the start of this level. Maybe give a warning that you won't actually get the power if you purchase it early, before you get the option to select which powers to bring along. Or something along those lines.
So, if complaining removed the debt feature - it was one of the main draws / goal to the game for me - can complaining put it back? Put it back! Add a cheap... er cheat option to remove it instead. + up if you agree.
Almost wish you could downgrade skills, XD. I seemed to be much more skilled at this game with just the first level of jump along with wall climb and double jump. As soon as I pumped up my jump, I'm falling much more often and it seems like I'm much less likely to pull off a wall climb successfully. I highly recommend upgrading jump last - after getting the first point of it, which I recommend doing first.
wouldn't be a bad idea to get rid of the lag at the beginning of the game explaining where the bad guys come from again, ever since, every game on nintendo, we should get it after the first time. or just guess eventually
