Heh. Review is really too big a word, it's just methoughts.
First off - I tried to run WinSetup and it told me it could't find the "Bear - net.exe" file, so I renamed the original exe. :
Common mistake, but worth setting straight - to rename your file, recompile it, don't just rename the exe.
First impression: very positive. I was quite surprised to see the Dizzy interface so well ported, kudos to you! The original Dizzy gameplay is also here, in just about it's entirety. Anyone who ever loved Dizzy should check it out.
One thing that I must say put me off, but that's because I'm a "Save Early, Save Often" guy (who uses his Spectrum emulator and general Sega emulators to save his state just before, say, making a series of hard jumps), is the lack of a save system. Anyone who, like me, will be put off by that as well, but if the game is short enough to finish in one sitting (which I don't know) and the player is willing to try his hand in at least one tricky sequence (the tree and the clouds, which made me quit after many attempts because I just couldn't do it), then it's a quite enjoyable experience.
"Cute" is the best word to define it. In a very positive way. The graphics are cute. The music, which is the original Dizzy music, is cute. The character interactions, what few I've seen, are quite cute. The gameplay is super-cute. The animations are very well made, very smooth.
There are only two things which don't really satisfy me as a gamer. The "jump up" bit works well enough, but sometimes just standing still and immediaty jumping to any direction made me jump up instead - or walk THEN jump, if that bit of walking didn't make me fall down, that is. I appreciate this was not easy to code into AGS in the first place, but if it were possible to fix this, it would be an added "bonus". Maybe a very short delay between pressing "up" and a direction, in order to see whether the player is really hitting just "up" or, a bit later, pressed a direction?
The second this is really preference. I'd rather have used ENTER instead of 4 to exit the interface screen. It's just more intuitive.
Well, that's about it. That's what methinks. I say, could you make a wimpy version (or add an "Easy" option) for us non-platformers who enjoy saving the game?
Oh, one thing I forgot to say.
WONDERFUL work! Here's looking forward for more!
