Alright, I just finished it, and I have to say, this really has potential. I like the fact that you can scale yourself up and down. This can potentially lead to some really interesting level design.
A few suggestions:
- Maybe decrease the gravity a little bit; the player feels a bit heavy.
- Some sections were a bit frustrating because you would just bonk your head and fall to your demise.
Besides that, it really is a good start for something that could be awesome, and I don't know why, but the death animation combined with the sound effect really made me giggle.
Good job!
