Thanks for your feedback! The playtest jumps into the beginning of the 4th level, which is partly why the intro is really long (a big story beat just happened at the end of level 3), but I'll keep that in mind and see if it's still an issue for a full playthrough, thanks!
Regarding getting experience from kills vs the experience crystals, it was a design decision I made to make the game a little easier to pick up (and also I didn't enjoy having to pick up the crystals from other games in the genre). That being said, it could be an option to enable/disable in the game in the future potentially!
The mushroom spores and colors have generally not been very well received, so that's something I'll likely have to think through after Feedback Quest to see if/how it should be improved, thanks for your feedback!
Using the mouse on the map makes sense, I think that's something that can be added in!
Thanks for playing! :)
