Hey Apost7, here is what I think (I did not get really far so I don't have very much to talk about):
- The decision of rewinding time while you jump is brave, but made it very difficult for me. When you play a platformer, you sort of plan out where a moving platform is going so you know when to jump. When you rewind it, it makes it very difficult. I tried it several times, but I think it rewinds faster than the normal speed, which made it very hard to plan out your jumps.
- Funny little character. Simple, but nice.
- Same with the sound. Simple, but does the trick.
A very small game. I could only reach 2 coins because of the difficulty so I would try to make it a bit more simple. Maybe add some checkpoints that if you fail, you don't have to do all the other difficult jumps as well. Have fun on vacation!
