Thanks guys for checking out the game.
I appreciate any and ALL feedback :) it all goes to making the game that much better. There are a lot of issues that have been touched on in the 'real' version but seeing things that may be annoying and are buggy in this little demo will be important to know so that I may check out whether or not it's an issue in the main build.
Again, really appreciate the feedback :D great eye for detail!
-Touching up on some of your questions -
Ubi won't be able to survive water at all in the game so he'll just pretty much explode or whatever animation i draw up in the final version so people won't sit through slow sinking.
When invincible he just plows through the enemies. I figured it would give a feeling of strength just being able to plow through and to also be able to quickly earn 1ups after killing a certain amount of enemies in that mode. I'll definitely place the star power up in areas that you won't need to kill enemies in order to progress
There will be a shops in the world map where you can use coins to purchase upgrades like extra heart containers, 1ups and other things.
Great idea about the re-spawn, i have to learn how to program that part in. I'll try it and then ask in the forums if i can't figure it out.
and the minor nitpicks aren't minor at all :D they're really useful. If a player feels any frustration due to the design then it's good for me to know so i can make this game as enjoyable as possible.
Thanks again for your feedback! It's very valuable!
