My Report:
This is what i think about it, Spoiler its long
Main
Liked the game but it misses some stuff, i understand that it in progress but i have some ideas to add in game
Note Attack Combinations
Then you have a lot of notes to spare filling all of them makes it boring, i would like to have a possibility having different combinations of note attacks, like orange and blue notes combined also can shoot 4 blue shots around the player with reduced damage, that would make the game more fun and have a lot of different attack patterns
Shops before Bosses
Sometime i get like 200 coins in first stage, but i never find a store before the final boss, make it so before a boss fight we had a store, so we can waste our money for upgrades
Notes in firsts rooms
Sometimes i reach the boss while still only having 3 notes, i would like that you will automatically after you complete first rooms you get a note, would make it a little more fair
Special attack at first notes Sequence
it looks wrong then your attack is the last one, cause some of them extend to next ones, and players tend to put notes on next sequence, and it visually looks wrong
Original Notes at same sequence
First, i would like to shoot a blue shot while having an orange explosion around me and able to do different combination (first suggestion) to cost 1 note, makes game little harder but you may add something for that (like my 3rd suggestion)
Enemy Ideas
Stage 3 bosses are repetitive , so what if we have a the bosses do this:
Mini boss
Shoots 4 homing missiles around himself, then shoots the player directly with 5 fast bullets
Boss
Has to shields covering 1/2 of himself with cant be destroyed. Will shoot 2 lasers ether sides of player and moving closer to the player.
After some damage to him dealt his shields will be destroyed and will try to shoot you with fast bullets, and then will summon 4 shooters which shoot with homing missiles, then will try to ram you quickly
Armored
An enemy, which has shields around him covering 2/5 of himself, shields cant be destroyed and they rotate around the enemy, player must shoot it from sides that doesn't have a shield
Shield-er
Supports other enemy by making immune shields around them (can just increase defense), must be destroyed to destroy the shields
Note Slower
An enemy with cant attack but will reduce the speed of your note template, making bigger pauses between shots.
New Notes Ideas
Fire note (took out of comments below)
Then enemy is hit with it will take low but continuous damage
Color: Red
Fire note Extra:
Combination blue: 1, Has an increased damage.
Combination Orange: 1, After death will explode, dealing damage. 2, will shoot 4 of those around the player with reduces damage
Combination Green: 1, Projectile goes quicker 2, will deal damage quicker over time
Combination Purple: 1, Shoots 3 projectiles
Bugs
Shooting enemy in stage 1
will not turn toward you for some time after shooting, the will snap right to look at player
Enemy going through walls
Sometimes enemy will go through rooms prop wall (not outsides one)
