Hi Jessica, thank you for taking the time to play my game :)
That was a lot of critique for one game, especially since you've found both versions of the game to be completely different (which wasn't my intention) :o
I'll have to look at both versions again to see what went wrong, as both versions should have the 'Game Over' scene, faster player movement, and less knockback from the boulders.
Hmm, you made an astute observation regarding the Jump sound, and yes, I'll be making the Player Mask/hitbox smaller, as currently CM can 'float' off the ground despite it's foot being in the air, so to speak.
I'll have a look at the depth for the signboards and creatures again, just to be sure which parts are dodgy :o
Where did you find the "?" mark? I seemed to have sailed right past it after countless time testing the game :o
I thought I had removed that exploit in the giant spider section, but I guess not DX
The tomes are meant to symbolise the qualities the alien needs in order to handle the challenges of travelling around the planet Earth, and are thus at the end of each obstacle area (Tome of Humility after getting through the boulders etc).
Hmm, that bit about not being able to get through the last door despite collecting all the tomes (in a different order, no less) shouldn't be happening, especially since the door is not affected by your not healing the giant wasp; you're the second person to have discovered that error, so now I'll have to add that to my list of things to test and fix :x
The alien's stamina regenerates over time as opposed to killing creatures to get health from them as the game was supposed to emphasise non-violence, not the usual 'attack everything in sight' philosophy of Metroid and Mario-like games. The 'attack' reducing your stamina over time was put in to make the giant creature sections a little more challenging, and will only work on the giant creatures as they need healing as compared to the smaller ones just going about their usual routines (the spiky ones fire their spikes when you get too close).
In order to heal the giant creatures, the alien has to put out it's arm to touch them, and gives away part of it's stamina in order to facilitate the healing. Methinks the signboard I put up for both giant creatures was too small D:
Yes, the game is not very challenging at the moment due to the time constraints I had while working on this game; I had intended the game level to be slightly longer and larger in the vein of Metroid-like games, which is why the puzzles and creature placements aren't as challenging as they could be. The arrangement of the puzzles and the creature placements will vary quite a bit from the last version you've played, since I'm still working on the game, so no worries :p
Once again, thank you for taking the time to play my game and spot all these bugs all over the place; Nintendo is very lucky to have you on their roster :)
