Successes:

• Successfully imported a double joystick to control the player, with the left joystick to control the movement and the right joystick to aim shooting direction and shoot bullets. 
• Created an automatic floor generating system. Randomly generate unlimited floors in our scene. 
• Designed a shop menu to shop for different super abilities. And the price doubles after each shopping to increase the difficulty level.
• Created healthbars for both enemies and the player. 
• Set randomly dropped collectibles, health and bombs. For increasing the health of the player and clearing all enemies on the screen.
• Added sound effects such as button click, shooting, shopping, player and enemy getting hurt, etc.
• Added a pause menu and created a complete game loop. 
• Added a timer to record the surviving time for each time.
• Made beautiful animations of enemies and the player, and made a beautiful enemy death effect.
• In general, we explored a lot of new tools and successfully implemented a lot of things we haven't tried before.

Challenges:

• Initially had trouble in building the game on our phone, but we eventually figured it out.
• Spent lots of time on designing the script for the right  joystick which controls the shooting direction of the player.
• Couldn’t find a complete tutorial video for tile generating system. Wrote 160 lines of code to fix the problem.
• because the style of a mobile game is new, there is a lot of things we didn't know how to do, therefore, we spent a lot of time learning, and finding resources.

what we learned

• We learned how to make 2D unity games on mobile phones and can successfully build it.
• Learned how to use a double joystick to control our player.
• We also learnt that research is often a huge part of game design, and we need to leave more time for it so nothing is too rushed.

possible future revisions

• Maybe add a best score system to store the player’s longest surviving time to encourage players to play more.
• Add more power ups or collectables on the floor, maybe even add some obstacles.
• Add more particle effects and animations to make the game even flashier.
• Add more items in the shops to have more variety and more strategy.
• Adjust the balance of the game more and maybe even add bosses once in a while.
