Neat concept for a game, slotting stats for the perfect run through the stage. I would have liked to see some freedom in creating a different build to go through the level in a different way as it seems you can only complete stages with one specific setup. The one game this reminds me of is Neon White in which you collect single use abilities to speed through a stage as quickly as possible. The genre doesn't quite match with yours as its much more action oriented but it's fun to think what could be adapted onto your project to make it flow smoother.
Some small nitpicks:
- The fire hazard has more horizontal collision than appears, I expected it to only be a tile wide but walking up to a wall and jumping straight up instantly kills if the fire is there.
- In the last stage I attempted to jump into the middle path but no matter how I held forward I couldn't enter the hole unless I did a shorter jump into it
- clicking to destroy boxes feels unintuitive, I expected to be able to destroy the boxes just by walking into them
