This is an interesting concept, and the visuals were undeniably very good. Well done!
Here's some things that detracted the overall experience for me:
- The reverse time button wasfrustratingly unresponsive, making it difficult to halt properly and often resulting in unintentional rollbacks beyond what I intended. This was very annoying! xD
- The spike collisions felt very unfair. Frequently, my character would be impaled mid-air, appearing to be floating. This issue was particularly evident during the double spike (celing and floor), where after about 80 attempts, I had to quit.
