Pretty game! I managed to beat the mosquito boss and got into the purple mushroom area. I liked the mechanics and the seed powerup is really nice! I couldn't spontaineuously find any key, so maybe I should explore more. Here are my suggestions so far based on what I noticed:
- The piano song is very relaxing and moving, but during the boss fight, maybe another more fast paced song would be appropriated;
- Some hazards and spikes instant kill the player, maybe the game could be more forgiving about the damage;
- While exploring the scenarios of the game, I personally found the botomless pits unfitting! But I don't know what to suggest here, because maybe the pits are necessary for the level design in particular, in some way that I don't realize yet. Otherwise, I'd suggest to try to minimize them;
- If the spear gets out of camera (player's view), maybe it could automatically return to the player;
- Maybe the player could destroy faster the mineral rocks;
- The "scenes" could have some hints or NPCs suggesting to the player where to go or what to do, in order to minimize the chances of players getting lost (I did!);
That's it! Beautiful project that you have in your hands! Keep it up and bring it to RELEASE!
