1. Level 1 is way harder than level 2,3,4. The boss is just right i think he is hard but not impossible.
2. The green and red circles I´m not sure if they work or what they are supose to do.
3. Nice and just right amount of stress in the music.
4. The upgrading of pets looks really cool and it is fun to try new combinations however it feels a bit hard when you can not choose your self when to upgrade i took alot of dmg cause i forgot where the enemies were :D
5. I like the artstyle of the game looks weird and scary at the same time :D
6. Over all i would easly buy this game with more levels and more pets :D
