Challenging to say the least! Nice graphics and fun concept.
Some other feedback / my opinions:
- As others have said the walljump took a while to figure out, but even then I continually lost the ability to walljump. Could be because of that the character lost touch of the wall or something.
- The fire felt like it started too fast and spread somewhat too quickly. If I missed a walljump somewhere I was toast (litterally?)
- For me it was impossible to not get hit by the fire on stage 2. Don't know if it's totally avoidable or not.
- It wasn't intuitive that you had to explicitly jump on the enemies. I lost some lives before I understood what I was supposed to do, and even then I could easily mis-time the jump and not bounce off the enemy.
- Another thing that wasn't intuitive was that you could jump off of the brown background tiles. When I came to stage 5 I had no clue what to do and lost many lives before I figured out that you had to jump off of the background. That could maybe have been introduced earlier in some easier fashion where you only had to jump off one of those? For example, a suggestion would be have only foreground and background things to jump from and replace the enemies with the background tiles.
