After playing a few stages: I feel there could be more items pickup during stage, not just power up, something like speed up, defense up, health powerbar up etc would be nice. First Aid random chance is a bit odd. First level has 0.6% chance but it seems to generate a lot more, and level 3 tooltip say 1.7999...998%. Again I just played a few stages, but Healing wave seems essential or OP in another way. Teammates could do more than just basic attack, maybe have their passives on. Hitbox seems a bit big for a shooting game.
Just played a few rounds, I like it so far. The graphic is pretty good. I think if something like map interface is added the game would have much more dept, rather than just keep playing and upgrade - which feel somewhat like Launch type of game.
Interestingly fun game. At first I thought the idea was not new and the graphic is rather out dated, but after playing a few rounds, the game play itself extended better than many other famous games. Although this game could use a lot of work but it has much potential. Keep improving it.
We will put that in the todo list to fix it, but basicly, please use drag instead of scroll in this game, scroll is mainly for zoom
